The Flex is sleek, simple, and fun to use, but shouldn't be mistaken for serious fitness technology.

The Fitbit Flex offers everything a person could want from a basic activity and sleep tracker. It’s fairly accurate, and prices have come down considerably to make it one of the cheapest ways to check out activity tracking.
Competition from the likes of the Jawbone Up range of activity trackers may be tempting but that means a more expensive band that's less versatile.
Clearly the little Fitbit has limitations, and it you’re looking for a device to get deep into training then this isn’t one for you, but if you’re considering dipping a toe into f... Full review
The Fitbit Flex is the most popular fitness tracker around. If you don’t believe me, look at the wrists of participants in your next meeting. It’s an attractive, understated device, and it’s one that’s comfortable to wear. Tracking 10,000 steps a day may have been proven irrelevant as a rational fitness litmus test, but it’s still a fun way to compete with friends and family while improving upon your laziness. Nevertheless, I don’t recommend this device for tracking runs unless you stick it in your pocket. Accuracy will always be suspect because of arm sw... Full review
The Flex wristband is practical and convenient but the question is – Is it comfortable while sleeping? We are concerned with its width of 11.1mm. To be precise, the discomfort comes from the slightly thicker end near the transparent window. If you are used to sleeping with a watch or a bracelet you won’t be disturbed by the 13 grams of the Flex.
About calculation accuracy we’d say that it’s relatively good. Not necessarily a 100% correct, but considering that it doesn’t use GPS the results are pretty good.
Unfortunately, Fitbit Flex doesn&... Full review
The Fitbit ecosystem is a great way to start using technology to keep on top of your personal health.
While the Flex is starting to show its age a bit, like a fine wine it has actually improved with time. The fact it's now more affordable is also a welcome one.
There is still the question of accuracy, with high step counts seemingly too-easy to obtain thanks to inaccurate algorithms.
The wristband itself could also use a little more work. It's lightweight and comfortable, but looks more like the watchband on a kid's watch than a truly stylish piece of tech.... Full review
The Fitbit Flex is a cool-looking, lightweight wristband that tracks and monitors your daily activity and sleep patterns. It syncs with a desktop dashboard and mobile app to give you up-to-date activity data in gorgeous graphs. You can compete with Fitbit-using friends and even upgrade to a premium Daily Trainer service. I found the Fitbit Flex gave me added motivation to walk or run that bit further, and keep an eye on my weight and fitness activities. It’s addictive and fun, and if that gets you moving more and generally fitter and leaner it’s better for you than most other co... Full review
At first glance, Flex seems little more than a souped-up pedometer. Since the only "activity" it can really measure is walking, it's no magical time-saver; I still have to painstakingly input any other exercise I do. It claimed that in "night-time" mode it could reveal my sleeping patterns, but the first night I wore it, it failed to notice I'd lain awake three hours with insomnia. Then there's the mystery of the scales. Sometimes, perhaps when I've skipped a day, they don't recognise me and measure me as a "guest user". The weight they record is almost invariably a couple of pounds more th... Full review
