    It's very comfortable and fits great. After a few days, you really don't realize you're wearing it.

    I really like this little tracker. It keeps me moving. I use it with My Fitness Pal, to track my food, and it synchs to my fitbit. It's really cool. - I love the sleep tracker too. Competing with friends to get more steps in is fun too.

    This device tracks your steps and encourages you to be more active. On setup you set a goal of number of steps you want to get on a daily basis. Quick access from your iPhone and you can see exactly where you are at. Knowing that you are so close to your goal gives you the drive to keep moving.

    Nice form of motivation as your progress is visually displayed throughout the day. Charger didn't work perfectly after a few charges and clasp could be more secure (lost/found once already). Otherwise a nice purchase

    I bought this as a replacement to a fitbit that is carried in a pocket. That one was lost when it fell out of a pocket. This one is easy to use and hard to lose! No notification when the battery ran low is the only complaint.
