  • Never thought Id want this but I do!!!!

    Such an amazing tool to aid in weight loss success. I love my new little friend FitBit. Its the most accurate tracker I have ever owned and believe me Ive gone through quite a few. I recently started wearing it to sleep. Tracking how many hours I sleep is incredible!! I also purchased the rose gold bangle to compliment my work attire. Definitely make the purchase if youre attempting to adopt a healthier lifestyle.

  • Exactly what I was looking for!

    Very pleased with the tracker, great phone app. Also love the ability to switch out bands, and even use the activity clip, bangle bracket, and pendent. My impression is that most people overbuy a tracker. Since it is the phone app that does all the work, the device is only as good as the app. I have been pleased that I was able to integrate the Flex 2 with all the fitness apps I use and love the options that this gives me. Exactly what I was looking for at a reasonable price; great starter!

  • I love this one!!!

    This is my third fit bit in a few years, and this one by far takes the cake! I have the Fitbit HR (well, two of them now after having issues and was issued a replacement) and it kept peeling the rubber off near the screen. I finally ordered this one after seeing that you can change the wristband and I can swim with it on. No issues! This one tracks my sleep and steps and I have it set to remind me to vibrate when I need to keep moving. I also have it set to where it will vibrate when someones calling or texting me. :) love this product!
