Update 12/8/15 - Fitbit just added a new firmware update for the sleep timer feature. Once updated it's no longer necessary to tap the Fitbit before going to sleep or when waking it. It will now recognize when you're inactive and have gone to sleep. It also has some new goal setting software in the app relating to sleep to make it easier to focus on getting more (or less) sleep. The graphic interface is pretty nice. I'm looking forward to using this since I've become something of a night owl and could really stand to get on a better schedule. One more thing to like about my Fitbit.
The update took about 5 minutes using my iPad and plugging my Fitbit into its charger while it updated. The whole thing was simple. A red arrow on the dashboard, in the sync area alerted me to the upgrade. I really like this new feature.

I bought 3 of these fitbit flex devices, one for myself, my husband and my sister. Before purchasing I researched several wristband devices such as the Jawbone UP, the Nike Fuel and and the Polar Loop. I also looked at the fitbit force which is a newer version of this band. The lack of water resistance on the force was a deal breaker for me. I wanted to be able to wear this band 24/7 and to be able to wear it in the shower or when swimming. That was part of what made it attractive to me. Also, after reading reviews about the clasp problems on the force and how many people lost them, I wanted no part of that. They are also quite a bit bigger and look clunckier. The wristband on the UP looked like it would catch on everything and had no display at all. The Polar had lots of quality problems. I wasn't crazy about the looks of the Nike. The display is nice and I can see how people would like them, but not my style. The fitbit flex, to my tastes, had the coolest look.

I've been using my Fitbit (and the website program) for over two weeks now. It's not a ton of time, but I have to say that I am absolutely in love!

While I had a bit of difficulty figuring out the ins and outs of the product (there's no user-manual in the package; you have to go to the website and click through the product to learn about how to go to Sleep Mode, how to charge, how to install, etc), once I did figure it all out it's been a breeze and surprisingly motivating. Just the fact that it's on my wrist reminds me (and encourages me) to get moving; I find I WANT to hit my 10,000 step goal, I'm DRIVEN to get there no matter how tired I might be, not to mention that the website is fantastic for tracking your calorie-intake and -outtake to really get a concrete understanding of your success in your weight-loss regiment. I love that the website charts my daily stats, from steps and distance to weight and progress towards my goal, and I have been religiously tracking myself, feeling great pride when I'm told I've reached my goal :D

The Fitbit Flex also has a sleep mode. Before I bought it, a friend of mine told me it would wake me up before my next REM state so that I wouldn't wake up groggy. Fibit does not say this simply because it's not true; it was a misrepresentation by my friend. BUT! The Fitbit does track how long it takes to fall asleep and how many times you 'wake up' (or move about) during the night, and it gives you a 'sleep efficiency' percentage that is actually really helpful. I've been enjoying this feature more than I expected because it's showing me that my sleep efficiency is TERRIBLE!!! 55% on a good day! AH! But it makes sense to me because I'm always tired and usually need to be in bed for 10+ hours to feel rested...

I am late 50s, office worker, pretty sedentary. I ordered the Fitbit because I hoped it would give me insight into how I burn calories, what I consume, and how I can be healthier managing both. But you can't do that without information ... and the wristband Fitbit silently tracks basic activities (walking, sleeping) that get logged to a Fitbit personal account. The input software for foods consumed is a bit fiddly but gets better after you create some custom foods (and since we tend to eat from the same basic of things, once entered they are easily plucked off the menu).

After two weeks, I can see exactly what I consume and how I can easily increase activity (without committing to gyms, etc): I am making a point of taking a brisk walk daily so that my daily calories burned are higher than consumed. I can track this easily on a PC, or Android tablet or smartphone. A big winner at such a small price!

I came across this device and bought it without even reading a review. After reading loads of reviews, I did wonder if I'd made the right decision, but I think for what the device provides, it is almost the best out there (the Fitbit Force might be the closest to best for this type of device, but it's bigger so I am happy with the size of the Fitbit flex).

First and foremost, this device is not for those who want precise numbers - if you want to know precisely how many steps you walked, precisely how many calories you burned, will intuitively work no matter what type of exercise you are doing, then you will be disappointed. If, however, you are using this device in conjunction with something like myfitnesspal to keep track of calorie intake vs calorie burn, and have a better idea of how active you REALLY are, then this device is really good!

As far as the pedometer goes, it is on your wrist, not your hip, so it's recording your motion more by your arm swaying as you walk. Suddenly, you are conscious when you are walking and holding a bag in that hand because you fear the pedometer isn't picking up your steps...

Pros:
*Motivates you - nothing like thinking, "Oh, I am only 2000 steps off doing 10,000 steps today to have met my goal of 10,000 steps" to actually do the steps! I found that my desk job meant at the end of the day I was not even getting in half of 10,000 steps per day, but with this device, I was reminded it might be better to get off at the station before my stop and walk home and get in those extra steps.
*The sync with myfitnesspal is a little buggy so has to be reset from time to time. But the synergy between the websites is good and really helpful.
