  • Love it

    I bought this because my other wrist counters never count steps when I'm pushing a stroller. I bought a ankle device that holds the fit bit one. Now I absolutely have no steps uncounted. This fitbit was easy right out of the box, plug into my tablet and in less than a minute was good to go, set up was a breeze. I feel this tracker is very accurate. I also feel there is NO tracker out there that is 100%.

  • A great way to track steps

    To start the new year I wanted a way to track my steps (for work-health care insurance incentive). Its easy to work with, I've got the app on my phone and can easily check my progress and recall my history.It's also become an asset for tracking my sleep and this was pertinent when I was having sleep issues to show my primary care physician.Sometimes I put it in my pocket, sometimes I place it in my bra if I have no pockets. I've tried the wristbands, but its easier just to clip it to my clothing.

    I love my FITBIT so well this is my second one. I have never had a problem with this device. The first one I bought when they first came. It is better than a a lickin and keep a tickin! LOL. No seriously, I forgot the device was attached on my running shorts and washed it and put it in the dryer. I continue to work just perfect for another year or so. Then, I purchased a second one. I like it better than the FITBIT HR. I am such a poor sleeper and I like that I can actually track my sleeping pattern.Thanks HSN.

  • great reminder

    I was trying to avoid getting any type of fitness monitor as a believed I was getting the in the correct amount of activity per day. Well I was incorrect. This monitor keeps me on track and focused.

  • My motivation

    I am loving my Fitbit. I wear it on my bra and can't even tell that its there. I love that I can access everything on my computer as well as my phone. I am trying to figure out what took me so long to finally purchase it.

  • Love it... Very Accurate

    I like this version much better than the charge. It counts your steps even when you are pushing a cart or stroller, or while you are holding something in your arm.

  • Awesome Product

    I have this Fitbit and I love it. I purchased it for my husband for Christmas and he loves it too. The sleep tracker was fun at first but we both got tired of it quickly. The app and friend challenges are very motivating and keep us on the move. The battery life is great, too. I charge mine once a week.
