had a one and liked it - clicked it to my bra. It did step, flights of stairs, and measured sleep by putting it in a velcro wrist thing you wore at night
I upgraded to a fitbit HR that you wear on your wrist. Its also measures heart beat and I feel it it more accurate for measuring sleep and I like that I can check my heart rate.
They are coming out with a new one, Fitbit Blaze to try and compete with the apple watch.
What I like about fit bit is the private challenges you can make with friends, you can join a group online that suits your needs through the fitbit site. I also belong to fitbitleague.com which is a free site you can join to compete against people all over the world by just simply being in the class it rates you or by joining tournaments.
