    Simple to use and easy to wear. Tracks steps and calories well. Is not very accurate for sleeping tracking.

    not as good as expected

    I had a Jawbone UP that I liked, except that you have to manually change it from tracker mode to sleep mode, and sometimes I fall asleep in front of the TV and I would like to know how much I sleep. So when the UP no longer worked (after four months), I traded it in for this. I am very disappointed with it. If I fall asleep during a movie, I can go back and "log" a sleep by setting the beginning and end times, and it will show that I fell asleep, but it shows me sleeping for much longer than I really did. Also, it will show me sleeping at night when I know I didn't fall asleep that early. And, unlike the UP, it doesn't show how much time is light sleep, and how much is deep sleep. It just shows "restless," which seems to be different, in that it's usually just a matter of a few minutes at a time. Step tracking, however, is accurate, and the food log is fairly easy to use and also seems fairly accurate, although it too doesn't show total carbs or total calcium, both of which are important to me.

    Fitbit Flex was easy to setup. The feedback it gives me daily for exercise, steps, calories burned, calories consumed, water and sleep habits is excellent.

    Fitbit Flex has been great to motivate me to take more steps each day and the reports are helpful and it is fun to see my friend's progress as well. Having trouble getting it onto the sleep mode and am not very fond of food tracking. Perhaps I am missing something, but it seems that I must enter each food and figure out the calories before this can be meaningful. A little disappointed about that. Have purchased one for a friend anyway.

    This product gave me what it said and what I was looking for. I have been able to link it to several other apps (myfitnesspal, mapmyrun, etc.) for additional tracking information. With the information, I've become more aware of my day-to-day activity and areas where I need to improve. I wish there were more mobile devices available to link. If I go out of town more than 5 days, I have to take the toggle with me in order to sync/track my info, or the data will be lost. I also wish there were additional ways of wearing it...the wristband is not appropriate for all workplaces or social events.

    Fitbit is slim and light. The battery lasts all week long. The hardware is great but the software for IOS is a bit weak. It would be nice if the dashboard was a little smarter. Since it's main thing is tracking steps and sleep, it should have the sleep button on the dashboard and not buried in menus.

    Fitbit is an awesome way to track your movement throughout the day and you can connect with friend. The only thing I do not like to the frequent outages the company has when trying to sink and it's product life is short. The longest I have had a Fitbit live is 1.5 years and my friends/family have the same issue. Buy the product replacement warranty.

    The fitbit flex so far has served me well, holding up to it's water resistance. However, if you're out walking and want to know your step count good luck. You get five dots. Period. No pulse monitoring, and if you don't swing your arms quite forcefully there's a chance it won't record. For a hands on worker, this is a huge flaw. Not crippling, but aggravating.

    This product is worth the money. It does it's job. It's waterproof (10 meters I think) so I put it on and only need to take it off when I charge it. I had the 'one' tracker before and while it was great I would for get it in my jeans or when I got out the shower. I ultimately lost it one day and couldn't find it. The Flex I don't have that issue. Some are disappointed it doesn't count stairs... That was never a 'killer' feature for me. I found it buggy on the 'One' and don't miss it with the Flex. The band does scuff somewhat easy... This is remedied by one of the killer features of the Flex. The band is interchangeable! The reason I rated 4 instead of 5 stars is for two reasons 1. The band color as of now is limited. And back ordered. 2. Lack of a screen that can tell the time. *they just announced the Force which is like the Flex with a screen for stats and altimeter for stairs. It DOESNOT have interchangeable bands and you CANNOT wear it in the shower. So I will be sticking with my Flex. I WOULD recommend the flex to my friends.
