Fast charging and protecting your smart phone’s battery life.
Do you want to charge your smart phone safely and keep the battery life good for as long as possible?
Are you surprised at how slowly your smart phone appears to charge sometimes?
Are you confused by the different cables and chargers around?
If you answered yes to just one of these, you’ve come to the right place…
Your smart phone’s Lithium-Ion battery is an incredibly sophisticated component that has evolved to supply reliable power for much of the day, safely, and for an extended lifetime of 1,000 charges.
Over those 1,000 charges, your battery will start to deteriorate and not yield the life it had when it was new.
A key way to reduce that degradation is NOT to charge it past 80-90% if you don’t have to and ideally keep it above 10-20%. This may mean charging it twice daily to keep it in that range and skipping overnight charging to 100%.
Like most people, you’ve probably got several chargers you’ve received with smart phone purchases over the years.
If you’re still using the charger that came with a smartphone just a few years ago, you need to change it!
👈 If you are using one of these to charge your iPhone 8 onwards, it’s only providing between 18-30% of the power your smart phone needs.
In other words, your smart phone could be charging up to five times slower than it’s capable of. 😳
Why Battery Size Matters
Smart phones now have 3-4X more battery capacity than just a decade ago. You may not have noticed the change as it has been a gradual change in line with smart phones getting thinner. While some of that capacity provides better battery life, more is used because smartphones now have giant screens and are more power-hungry. What could charge a smart phone a decade ago will only give you a fraction of the power needed now.
To understand if your smartphone is getting a meaningful charge, you should measure it in terms of the % battery boost in a particular timeframe, e.g. 0-50% battery in 30 minutes.
Using an old charger with your new smartphone may take over 2 hours to get a meaningful charge. Of course, that’s not a lot of use when you’ve only got 10 minutes to get out of the house.
So what’s the answer?
Faster charging. The first iteration was QuickCharge from Qualcomm. This allowed slightly quicker charging using the micro-USB cable. However, it was proprietary and generally limited to specific Android devices that used Qualcomm components (by no means all). Plus, it was limited to the inferior micro-USB cable, which breaks easily.
Now USB is leading the way in providing fast charging standards developed and agreed upon by a cross-industry group, including leading vendors such as Apple, Samsung, and Google, as well as chip companies such as Intel and Texas Instruments.
They developed a better cable ending – USB-C – and the next-generation USB charging technology known rather boringly as USB Power Delivery (PD). It’s now considered the only true Fast Charge technology for smart phones, which is also compatible with laptops and tablets.
How does USB PD work in the simplest terms?
Well, it’s actually quite straightforward. Power, measured in Watts, is simply Volts multiplied by Amps. So, with old USB charging, you might have between 5W and 12W of power (at best). But with USB PD, chargers can go all the way to 100W – over 8 times more power or 20x more power than the typical 5W chargers many people still use! (Remember that Apple charger above?)
Most smart phones today charge in the 20W-45W bracket, so a PD charger offering anywhere from 20W to 45W is good enough. But if you use a higher power charger made for a larger laptop or tablet, that’s even better. Of course, you don’t need a 100W USB PD charger, but neither will it do any harm.
USB PD continues to develop and is being stretched to 240W of power in the next generation. This could permit e-bike/e-scooter or power tool batteries to be charged while also permitting charging some of the largest laptops or powering small desktops.
Qualcomm has adopted USB PD in its QuickCharge4 standard, meaning devices supporting QC4 will also support USB PD chargers. In addition, Apple’s Lightning cable (with a USB-C adapter on the charger end) also supports USB PD chargers.
Am I using USB PD Fast Charge today?
If your charger has a USB-C port, it may be USB PD, but not definitively. If you can find the specs, look for USB PD to be mentioned and voltage levels other than 5V (e.g. 9V) and/or power of 18W or more.
If your charger has a USB-A socket, it is definitely NOT a USB PD fast charge charger. And just because your smart phone has a USB-C socket does NOT mean it’s a smart phone capable of USB PD Fast charging.
And finally.
We’ve not discussed loads of geeky terms here, such as Wh, or mAh but it is REALLY useful to understand a very simple relationship. Watts = power. A Wh or Watthour is simply the amount of power that can be sustained for one hour – so you can be a powerful runner with a quick sprint, but a one-hour run is the power you can maintain for one hour – “energy”.
In electrical terms, there are two key components that make up power; Volts and Current (amps). Multiply the two, and you get the Watts. Maintain that for one hour and you get Watthours. So, 5V * 1A = 5 Watts. Maintain that for 1 hour and you get 5Wh of energy – a smartphone that runs at 1Wh will get you 5 hours of usage.
So there it is. Fast charging in a nutshell.
One Charging Cable – A Great Idea?
On the surface, what is there not to like? Well, quite a lot actually.
Bureaucrats and politicians interfering in technology innovation is never a good thing, and this is no exception.
Have we suddenly reached peak cable where no further innovation is necessary?
There are some reasons for having a universal cable – to reduce e-Waste, extend the life of a charging system and simplify things for consumers. But, if the result stifles innovation, these small benefits are far outweighed.
The EU attempted this several years ago when the common cable type was Micro-USB. Was this the ultimate cable? It certainly wasn’t. For starters, it has a non-reversible end which causes damage to cables and devices as users struggle to insert it the right way up. Micro-USB continues to limp on but is dramatically declining, accounting for less than 10% of the phone charges we deliver.
If Micro-USB had been mandated years ago, we’d be stuck with an inferior solution. We wouldn’t be seeing the increasing number of larger devices that use USB Power Delivery charging, which is impossible with Micro-USB. We’d also be stuck with bad chargers for phones needing alternative chargers around our homes and workplaces for other devices instead of sharing cables.
Forcing such a change will also render equipment useless, potentially creating more e-Waste and further consumer cost. For example, the car industry works on a much slower innovation cycle. If your AV equipment in your brand new car supports your Apple iPhone via Lightning, but that system cannot support your next phone, what will that mean for you and your vehicle?
How can EU politicians judge the limits imposed on technology vendors and prevent us from choosing something else when those vendors are incentivised to make our lives better?
We firmly believe any intervention in this area is bad because it will stifle innovation and potentially productivity by limiting what innovations can be deployed.
Wireless charging doesn’t plug into the phone but requires an alternative connection. If that’s allowed, why not something else? We’d be forcing our devices to have ports that limit waterproofing and dust proofing if it’s not allowed. There may be details in the EU proposals that outline these, but we can’t be sure since the situation is evolving.
If the EU IS determined to mandate something and reduce e-waste, then surely it should be focused on the other two elements of charging:-
- The charger itself has considerably more environmental impact than a cable
- Having a standard protocol such as USB Power Delivery
However, this too requires caution as USB PD covers everything from a 15W charger suitable for small phones to 100W chargers for laptops. Indeed the next version of USB PD will support 240W charging – capable of charging the most power-hungry laptops as well as e-bike batteries, power tool batteries and a whole host of other things.
In summary, the EU should not interfere in areas that have the potential to limit innovation and productivity. But if they have to do anything, then perhaps the focus should be on quality chargers that are safe, reliable and power-efficient and that use a standard charging protocol such as USB-PD. This would be far more beneficial to consumers and the environment alike.
The EU should also lobby the USB Implementers Forum to make sure consumers understand that charger, charging standard, and cable permutations are many – and all impact performance.
Change doesn’t have to happen overnight – but to prevent change altogether would be disastrous.
Our Sustainability Strategy
Sustainability and the Environment are dear to us all at ChargeBox. However, these are not just words; we are taking tangible actions to make our company sustainable and make the products and services we provide to our clients sustainable.
In 2021, ChargeBox committed to NetZero by 2030, which can be seen on the SME Climate Hub. Also, in 2021, ChargeBox was part of the first cohort of businesses to go through the BetterFutures+ programme, developed by West London Business, with the backing of the Mayor of London.
The mix of workshops designed by Imperial College Business School, a carbon calculator and a consultancy project focused on embedded carbon inside ChargeBox, has given us an accurate insight into our emissions and those created by our suppliers. As well as those taken on by our clients when they purchase or rent our ChargeBox solutions.

“With the addition of a heat pump, solar thermal hot water, and solar PV, I’ve chosen to make my own dwelling zero carbon and invested in a wind farm to produce 120% of the electricity required – even while purchasing renewable energy. For as long as I can remember, I have cycled to work and back every day.” Ian
We are especially delighted to work with clients committed to NetZero. And we will provide any information and mitigations to you to help you achieve your commitments and interim goals.
Like any business, we have our emissions and waste. However, we have taken significant steps to use renewable energy for our premises and recycle everything we have to dispose of with zero landfill. These efforts really help on our Scope 1 and Scope 2 emissions. We also have a cycle-to-work scheme and encourage our staff to use public transport to support deployed ChargeBox stations.
However, we learned from our BetterFutures+ experience that our biggest challenge is to reduce our Scope 3 emissions – those we do not directly output – as they are emissions of our suppliers and clients as a consequence of providing the service. We estimate these emissions to represent over 93% of total emissions, and so represent a far bigger prize to impact than just our own direct emissions.
To provide the World’s best charging solutions, we have developed great designs and user experiences built around quality materials and leading-edge electronics. Materials (e.g. steel, stainless steel, aluminium) and computer boards, wiring, PCBs etc., all have a sustainability impact and emissions impact. Because we control those designs, we have calculated the impact of embedded carbon at manufacture and lifecycle emissions during use. We can also reduce those emissions through supplier choice, component choice, design changes, and recycling/reuse, making our solutions more sustainable.
Here are the things we’ve already done:
- Since 2019 we have manufactured all of our solutions at a UK factory, minimising long-distance logistics and ensuring control of what goes into every ChargeBox. In addition, our factory has a solar PV system that generates over 0.5MW of electricity – larger than 150 home installations.
- Our primary manufacturer works with UK and European suppliers to source primary metals and is constantly looking at ways to choose lower emissions and more sustainable materials, particularly aluminium produced using renewable energy or newer processes for stainless and mild steel.
- Because of these actions above, we estimate that around 95% by value of components and work to make a ChargeBox is kept within the UK and EU. With competitors often sourced from Asia – often from countries with high carbon electricity generation – this figure is likely the other way around for them. By keeping the value locally we help the UK economy with well-paid jobs, while also being much more in control of emissions during manufacturing. Emissions from long distance transport – usually by high emissions cargo ships are almost totally eliminated. By the time a ChargeBox reaches our warehouse – we’re miles ahead on embedded emissions.
- We have always strived for low-power components. Our Raspberry Pi main computers – also designed and manufactured in the UK – have extremely low power usage. And our other electronics means that when in idle mode and not charging any phones, ChargeBox will use as little as 6W of electricity – less than 1/10th of an old lightbulb. Our larger units with top screens idle at around 22W – still less than 1/3 of a lightbulb. Charging a phone uses comparatively little power, but 1 unit of electricity is enough to charge around 30-40 phones, 15 tablets or 5 laptops*.
- We are on our 3rd generation of cable enhancement. A typical Apple iPhone cable may only last for 200-400 uses, but our cables last for over 4000 uses. Fewer cable changes saves materials and reduces service visits to fix while also improving availability.
- While our 3rd generation ChargeBox has the best and most reliable design ever, with almost everything changed, we have also recognised that some components from end-of-life solutions are still just as good and can be re-used. We give a lifetime warranty on these components and have reduced the embedded carbon in our latest stations by 15%. We will continue to iterate our designs and choice of materials suppliers to reduce this figure further.
- Our IT services are all cloud-based, and we use a supplier that will be carbon neutral before the end of 2025.
- We continue to work with our primary suppliers to encourage their own NetZero journey.
- We now offer to all our clients who are upgrading or retiring units to responsibly recycle, retest and reuse and can provide appropriate guarantees to clients. You can therefore be sure that metals used in any ChargeBox will be recycled, and electronics and wiring will either be re-used, repurposed, or responsibly disposed of. In addition, we are committed to incremental reductions in the embedded carbon of our solutions over their lifetime. We will also ensure they are not a burden to our clients at end-of-life.
- Many of our solutions are heavy and require complex logistics to ship across the UK or abroad. We outsource much of this to professional logistics and delivery companies. Right now, there are no suitable zero-carbon methods for moving equipment long distances, but we will continue to work with suppliers to adopt such practices when they become available.
- When we do our own deliveries, we are now trying to source lower carbon or zero-carbon transportation. This is easier around our base in London, but zero-emissions logistics for moving our heavy items around even short distances are not there yet. However, with the steps we’ve taken, we estimate that we will use 10% less carbon in our logistics emissions in 2022 over 2019, and we expect these savings to accelerate.
- We use a protective wrap on most ChargeBox solutions for permanent installation or events. This helps extend the unit’s life but is also used for sponsorship and branding. We sourced the most environmentally friendly wrap solution from 3M via a key supplier who is committed to sustainability. We also now do this in-house, eliminating shipping of panels there and back.
We are all on this sustainable journey together. We’ll be sharing regular updates and blogs about our progress. If you’re interested in our journey, follow us on Twitter, LinkedIn and Instagram to see how we’re getting on.

Smart Lock vs PIN
In this digital age, is it surprising to learn that key security still firmly trumps a PIN or a futuristic biometric system?
We patented our smart lock for charging lockers back in 2013, and it is still as relevant and market-leading today.
We thoroughly explored the alternatives in our quest for the ultimate locker security. But even now, in 2022, we still get asked about PIN lockers and how they compare.
To understand the limitations and benefits of a PIN-based system, we built one as a prototype and put it to the test. We trialled it in a Central London location and then sat back to observe usage on the CCTV.
On one occasion, we watched someone using the locker correctly, followed by someone else getting up from a nearby sofa, going to the same locker, typing in the PIN and stealing the device. The phone owner had done nothing wrong but found their device gone through no fault of their own.
This is just one example I hear you say. However, that alone doesn’t make key security better than a PIN. Surely there are ways PIN systems could be as good or better than a key?
We think not. Here are seven rock-solid reasons why key trumps PIN every time.
Security:
- It is pretty easy to see peoples’ keystrokes, especially when they’re unfamiliar with the system and do it slowly. Typically a user-selected PIN must be confirmed, which gives a thief a second opportunity to spot the PIN.
- Even with a six-digit PIN, anyone can remember a sequence of 6 digits. And it’s super-easy for someone standing behind to video a user entering a complex PIN.
- Preventing users from choosing common PINs (e.g. 123456) will reduce successful guesswork. Still, it’s not enough unless you also reduce how many attempts are allowed. This can create another problem, though – locking the genuine user from retrieving their device!
Ease of use:
- It is significantly more time-consuming and tricky for users to create a PIN (that passes the uniqueness test). You can easily spend a few minutes setting up a PIN system – while it’s just a few seconds to use a key. That gives more charging time and means the machine is quickly available for following users.
- What happens if a user forgets their PIN or gets locked out? Staff interventions to release the device and put the locker back in service. Even if this happens with 1 user in 100, it means staff interventions at busy locations every day.
Practicality:
- Without clever design, a PIN system makes it easy for a user to lock an empty locker and leave it that way, reducing service availability. Of course, this won’t happen everywhere, but anti-social behaviour is a risk in specific locations.
- What happens if a PIN security machine loses power (the site loses power, or the machine fails)? If this happens, there are two choices – open all the doors or keep them all locked. Neither answer is satisfactory, though the former is, of course, the worst. Would this also happen with a ChargeBox? Fortunately, the answer is “No”. If the power source goes down, all you need is the key to retrieve your device, as it’s only a mechanical process to unlock it.
But come on, there must be some bad things about a key?
Well, you have to carry it around with you, and it’s possible to lose one. However, in our experience of charging over 50 million phones, this happens to less than 1 in 50,000 charges. The host site can open the locker with an emergency key and retrieve the device subject to certain security checks if it does. All the while, our systems record every event down to the second and transmit this to our servers – e.g. door locked, charging started, cable disconnected, etc. So we can back up any truthful story with our audit trail, and if someone is not telling the truth, we can see that too.
So OK, a PIN is maybe not such a great idea, but biometric security is undoubtedly the future. After all, that’s what I use on my phone these days, and they can’t steal that, and I can’t lose it.
We’d welcome reliable biometric systems, but it’s far from reliable. Fingerprint-based and face profiles are two common biometric systems. You know it takes time to set up if you’ve used these before. And these are state-of-the-art systems by some of the world’s best technology manufacturers. Using biometrics, a phone charging locker is slow to use, insecure, or both.
Even worse is the assumption that a biometric reader will remain clean and fully functional. Used many times a day with many different fingerprints – dirty, wet etc., will affect performance. In addition, users will not be able to use the locker or retrieve their device resulting in more poor service and high staff interventions.
And of course, just as for PIN, if power is lost, so are your chances of retrieving your device.So, that is why we use keys – and we suspect why you use keys to secure your property too.
Apple is raising security levels with iOS 12
iPhone users with iOS12 or later may see messages prompting them to unlock their phones when plugging into ChargeBox charging stations.
Since the San Bernardino shooting in 2015, and the ensuing legal battle with Apple, there is a constant tug-of-war between the California tech giant and governments around the world about encryption and security.
The Governments try to compel Apple to create special software or loopholes that would allow them to access data on a locked iPhone in cases where they see it for the greater good of the public. Apple, on the other hand, is adamant not to compromise on its customer’s privacy.
In the meantime, there are third party suppliers of hacking devices that allow law enforcement to circumvent iOS encryptions and access things like lists of phone calls, emails or contacts.
The exact inner workings of such hacking devices are not publicly known, but Apple tries to curb their use nevertheless with changes in their security protocol.
When a phone is plugged into any form of USB device with a potential data connection, you will receive the following message: “Unlock iPhone to use accessories”. Before the phone is unlocked, no data transfer whatsoever is allowed. From an individual’s privacy perspective, this is a great move, and here at ChargeBox, we certainly applaud this development.
However, this brings a new set of issues for customers of our public charging stations. ChargeBox very much values every user’s privacy. We are fully compliant with the new GDPR guidelines and would never attempt to take personal data of any phone plugged into one of our stations. However, to ensure the best USB optimized charging experience, there is some standardized data transfer between devices and our charging hubs, negotiating charging capabilities and speeds. You can see more on our privacy policy page which is here.
This means, anyone using our charging stations that has iOS 12 or newer installed, will be prompted with a message that could wrongfully raise privacy and/or security concerns. You will receive a charge irrespective of whether you unlock or not, but it will help us to serve you better, especially in the rare event of any challenges you have such as losing your key.
Rest assured, we have only ever cared about optimally charging your phone, and always will!
How smart technology is key to improving the passenger experience within airports
Worldwide airports are always looking at ways to improve the passenger experience, and it is clear that introducing smart technology is a way of achieving this. Travellers are becoming increasingly reliant on their devices to guide them through their journey. They are not only using their devices to pass the time but also for mobile ticket, live travel updates, mobile payments and mobility platforms such as Uber.
In a recent article by the Financial Times "Airports fight back against online turbulence", it reported that Singapore's Changi's Terminal 4 building is embracing smart technology to improve passenger experience but also help drive revenues.
Over the past 5 years, ChargeBox have been working with one of the world's busiest airports, Paris Charles de Gaulle Airport, to provide free mobile device charging to their passengers. With 49 stations installed and over 2.5 million charges delivered since installation, Paris Aéroport is heavily invested in improvising the passenger experience.
"Our customers appreciate the simplicity of using ChargeBox, thanks to the presence of the smart lock and the instructions which are universally intuitive." - Marketing & Services Manager, Paris Aéroport.
Research has shown that having a low battery increases anxiety levels, leaving travellers feeling dissatisfied. Edward Arkwright, Deputy Chief Executive Officer for Groupe Aéroports de Paris stated that "The worse situation for retail is a worse passenger experience...if we improve customer experience, we will improve all economic models."
In the ChargeBox Return on Investment Study, it was shown that people who used ChargeBox spend on average £35 more than those who didn't and 92% of users felt positively/very positively towards the brand.
Providing charging services alongside smart technology is vital to alleviating the stress that comes with travelling, it enhances the overall customer experience and powers the travellers engagement.
Who said the high street is dead?
High street stores have always faced certain challenges, but the current retail climate has seen some of the best known brands disappear from the high street altogether. In this changing marketplace it is the innovative and forward thinking retailers that are continuing to thrive in these difficult times.
In today's digital world consumers are visiting stores less, and shopping online more. So what can the high street do to entice customers back through their doors? While there isn't just one solution, we at ChargeBox believe that providing a positive customer experience is key for retailers to differentiate themselves from their competition.
The Digital High Street 2020 Report released in 2015, states that "because consumers have compelling digital options, physical stores are making their locations interactive and engaging in order to attract footfall and justify costs of stores operations."
As the market leaders in public device charging, we've always known how impactful providing a charging service can be for retailers. We recently commissioned an independent study in conjunction with a major British department store to measure this impact on customer behaviour.
The findings not only demonstrated that shoppers who used a ChargeBox stayed nearly half an hour longer but also saw the average spend of a user increase by £35. Offering charging services clearly enhances the customer experience, but also provides a measurable ROI for the retailer.
Smart retailers are realising that it's no longer just about the products they offer, but more importantly it's about the entire shopping experience. These additional services are the key to retaining their loyal customers, and gaining new ones.
"At Fenwick we are focused on providing outstanding customer experience and a great in-store experience. Providing free charging via our ChargeBoxes is one way we deliver this."
Whilst figures indicate a decline in the retail sector, having a physical store presence is still vital for large retail brands and it's clear that retailers must adapt and evolve in order to thrive. Providing a positive in-store customer experience in this fast moving digital age will drive footfall, brand loyalty and ensure the survival of the high street.
Improving the passenger experience with ChargeBox
Technology is becoming a necessary part of our transport experiences. The smart phone allows passengers to check train times, purchase and store tickets and continue to engage on social media.
Providing a mobile phone charging infrastructure is a necessity when expecting customers to use their devices for the above. We know that just providing power sockets is no longer enough.
"We have worked with ChargeBox for a number of years now and have always been impressed by their service and support. The products are very popular with our customers and look great in our environment. We would have no hesitation in recommending them to other businesses."
Edinburgh Bus Station
Over the years, ChargeBox have worked with multiple clients within the travel sector but back in August last year we installed 4 of our Charging Tables to a major British Train Station. Since installation the charging solutions have provided over 235,000 charges to their passengers.
With travel hubs continuing to find new ways to innovate and enhance the passenger experience, it is becoming more apparent than ever that offering free charging will improve the overall passenger experience within the station.
How can ChargeBox improve your in-store customer experience?
The in-store customer experience is vital to sustaining a strong presence on the high street and retailers are always looking at ways to improve this.
As online sales continue to grow, attracting visitors back to the high street stores is a constant priority for the retail sector and having charging solutions is a way of changing their behaviours.
In John Lewis' 2017 retail report, they talk about "shopping journeys [being] a mix [of] online and physical experiences" and how "customer service remains the glue that holds the entire experience together."
ChargeBox has 12 years experience in offering public charging and we understand the importance of providing a charging service to consumers in todays digitally driven world.
Over the years we've built some fantastic relationships with leading retailers such as John Lewis, TKMaxx and H&M. Year on year they continue to see the benefit of having an in-store charging service.
"At John Lewis we've always been passionate about providing our customers with the very best service, and offering free charging in our shops is one of our ways of enhancing customer experience."
Receiving positive feedback from our clients is always great, but we wanted to prove that what was being said was true.
Back in August 2017, ChargeBox commissioned an independent study to measure the benefits gained from free charging. The results were outstanding!
We found that having charging services not only increased dwell time, but also had a positive impact on basket size, spend, footfall and customer satisfaction.
"At Fenwick we are focused on providing outstanding customer service and a great in-store shopping experience...A charged battery enables them to stay connected with loved ones and allows them to enjoy an omni-channel shopping experience."
ChargeBox are aware that each retailer have their own objectives and bespoke in-store aesthetics, so we have designed a range of solutions, both lockable and open, that fit any requirement or environment.
With our wealth of knowledge and expertise, ChargeBox make sure that we can provide a solution to match whatever brief is provided by our clients, with customer experience being at the forefront of our minds.
ChargeBox Return on Investment study (August 2017) – Ink Research Limited
ChargeBox commissioned an independent study in conjunction with a leading British department store to measure the benefits gained from free charging.
What effect does free charging in a retail environment have on customer behaviour?
- Does it make customers dwell longer?
- Do they spend more?
- Does it increase footfall?
- Does it improve the customer experience?
- Does it positively impact customer satisfaction?
These are the many questions that we have been asked by retailers since we launched our first free charging stations in Westfield Stratford back in 2012. Of course, at ChargeBox, we have always believed that the answer is Yes to all of these questions. However, we were finding that more often than not providing amazing usage statistics alone were not enough to convince clients that the tangible and intangible benefits of offering a free charging service outweighed the associated costs. After all, how do you put a value on customer experience?
Ink Research Limited spent 3 days in-store and during this time they interviewed 214 shoppers of which 81 were ChargeBox users and 133 were non-users. Not only did the results confirm our beliefs, but they exceeded our expectations.
