  • Exactly what I needed

    Great product! Holds charge for several days without recharging. Does just what I need. It replaced a much more expensive Fitbit that fell apart. It was capable of doing so many things that I wasn't using. This is perfect. Nice basic unit.

  • Justvwhat I was lookingbfor!

    I have been waiting for an affordable fitbit that I could use during water aerobics. I have been wearing this about a week and it works in the water. I like the sleep tracker and alert in the morning..also the gentle reminder to get up and move. Great fitbit for the money. It is definitely is motivating me to move!

  • Didn't buy what I wanted

    I gave this 5 stars because everyone I know, who has a Fitbit, LOVES it. I just selected the wrong one for me, so I sent it back. Now that I'm more educated I've reordered.

  • This is Really Great!

    I normally wear an Alta, but decided to try this design, and I'm so glad I did! I love the slimmer band, and it fits so snugly, it's really comfortable. It comes with two band sizes, I use the smaller. It was super easy to set up with the FitBit app, I compared the count to the Alta and it's right on. Very simple but it's all the info I need: steps, sleep time and looks great. Accuracy is perfect...I love it! Thinking of buying some as gifts.
