    I wear my Fitbit all the time. It only comes off to recharge the battery. It keeps me challenged to get those extra daily steps in to either meet my goal or push on. Being able to create a group of friends and compare each other's status is an excellent motivator. I'm in love with my Fitbit!!

    Helped motivate my technology loving husband to be more active and accurately tracked his activity during the day. Link with myfitnesspal (more extensive food database) for best results. Add friends and family to friends on Fitbit app for a little friendly competition and extra motivation! :)

    I really like this device and it being a wrist band makes not loosing it a thing of the past. (I lost my fit bit one.) Syncs with app like myfitnesspal and edmondo make this a great app to workout and keep track of health. Your phones needs BT 4.0 to sync wirelessly to phone but can sync with computer with dongle. Sleep mode is easy to activate and silent alarms are nice for couple who wake at different times. Great for taking a nap in a quiet area.

    This tracker meets most of what I want in a fitness tracker. I will,however, be getting the one that has the time on it. I would recommend that one. Oh, and I hope the fixed the charging issues. have to wiggle mine over and over again to get the charging process to begin.

    I just wanted a basic fitness band and this fit the bill. The fact that I can change bands is a plus. I have a nice watch so I didn't really want that feature. The only thing I don't like about the Flex vs. more expensive versions is the sleep tracking since you have to start and stop it. However, that isn't a big concern for me.
