Rated 1 out of 5 by Piece of JUNK!! I only marked "excellent" for style because I like the size and the ability to change bands. The price isn't bad either for what all it does, when it actually works, of course. Other than that, this thing is junk!! I purchased a Fitbit Flex last October. I didn't get around to setting it up until mid-November. Around February 23rd is when it quit holding a charge. Fitbit sent me a replacement. April 26th is when I emailed them about that one doing the same exact thing. So they sent me another replacement, which did last the longest, but still not even 4 months. I'm glad I held onto my receipt because I'm taking the original back to Kohl's. I'm not even sure I want to stick with the Fitbit brand. 09/01/2015
Rated 5 out of 5 by Love the Fit bit flex I am having so much fun with the FIT Bit Flex, my daughter and I have challenges each week. And I like have the clock feature so I don't have to wear a watch as well 09/29/2015
Rated 5 out of 5 Don't have to worry about losing this I had the small one that clips and kept losing it and misplacing it. For me this is so much better, I put it on and never think about it the whole day. I only take it off when I swim or shower. I can use to track my sleep time. I can set a silent alarm to vibrate when I need it. Only thing is this requires more charging than the other one. 09/18/2015
Rated 3 out of 5 by I enjoyed it when it was working Right now I am having problems with my Fitbit I am looking for some troubleshooting ideas on line to see if it can be reset or not. It's still not working 09/10/2015
