First step tracker I've had that easily works
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.TheI Fitbit flex is all I expected and more. I feel more motivated, to keep active now that I'm wearing my wristband. And get occasional updates as to my progress in obtaining my goal of so many steps each day. It also keeps track of my sleep patterns with is quite interesting. It was extremely easy to setup on my mobile phone and computer and with Bluetooth syncs automatically Only drawback. is the wristband is a little uncomfortable at night. All in all I am extremely pleased with my new Fitbit

Love it
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My Fitbit keeps me in line and helps me hold myself accountable for my fitness and my fitness goals. I love that I can challenge my friends on a daily or weekly basis. It makes fitness fun. The only reason I don't give it 5 stars is because it comes off easily and I've lost one before. I recommend purchasing a "bitbelt" to insure your fitness investment. The Fitbit is worth it!

Good tracking device
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This product is great for tracking calories taken in or out, the number of steps taken, water consumed etc. it's also nice as you have historical data to track how much more or less you are doing. I'm unsure of the accuracy regarding an active activity such as biking but it at least gives you an estimate.
