Rated 5 out of 5 by Love my fit bit I've had my fit bit flex on for several weeks and love it. It definitely encourages you to think about moving more so you can get to your goal. The silent alarm definitely works. I don't agree with the sleep reports because it doesn't tell you if you're getting good REM sleep it just lets you know you're not moving at night so it counts you as asleep. It says it is water proof but I don't shower with it on and haven't tried swimming with it yet. As long as you keep the "background sync'ing" off and manually sync it when you want to you will save a lot on the battery. I only have to plug mine in once a week/ every 9-10 days sometimes. 05/27/2014
Rated 4 out of 5 by Does not have a clock or screen to see info quick I had the regular fitbit that you clip onto your clothes but when I saw that this one was waterproof and looked like a watch -I got it--BUT it does not have a clock (why would I want to wear something on my wrist all day AND ALSO a watch) this particular tracker also LACKS the stairs climbed feature that the older one had AND you cant see the information on this one with the touch of a button like the older one--this one only has the little lights to let you know how close you are to the steps goal ...Im going to wait until they come out with a new one with a clock/waterproof/stairs climbed feature...but it does work very well if you dont care about the things I mentioned 06/16/2014
Rated 4 out of 5 by I have recommended this product I have recommended this product, but now am experiencing some glitches with it. They're not major, but when I go to their online community, the problems are common glitches that many people have. It's a great way to measure how many calories you work off vs. how many you eat. I also like that it measures the quality of my sleep. The glitches are that I can walk 10,000 steps per day and some days that will equal 5 miles and some days it won't. Also, it awards you badges for achievements, and I received a 250 mile badge LONG before it was due. The A/R part of me was bothered by that, but I chose to focus instead on the progress. I can tell how many days it takes me to burn the 3500 additional calories in a pound. 07/17/2014
Rated 3 out of 5 by Not what I expected I was really excited to get my Fit bit. I have always wanted one but they were too pricey for me. After talking with a co-worker(she has one) I took the plunge and got my own. I loved that it synced with my iPhone but aside from that. The steps were not accurate for me. I adjusted my stride many times and it never came close to the steps on my iPhone as to accuracy. It also said that the charge should last at least a week(barring the use of alarms or other features). My first charge lasted 4 days, then when I charged it a second time all night, it was only half charged. I was finding that no matter how I had it positioned on my wrist, I was constantly catching it and a few times almost lost it. I just didn't feel that it had much to offer that my iPhone didn't. So, I returned it an I am happy with using my iPhone and pacer app. 02/12/2015
