You need this! I absolutely love this product! It's not much bigger than a regular watch so it doesn't draw a lot of attention (a huge plus for me at work). I can't always have my phone on me, but this sends me text and call notification, which is awesome! There are so many features to this FitReact, and every single one is as amazing as the last (sleep patterns tracking, heart rate tracking, etc.) I highly recommend this to others. I have had mine a week and haven't had any issues with it. It's very accurate when worn as instructed for workouts. Best investment ever!

I am so glad I bought this! Seriously thought I was not going to like this but I think I'm addicted to it!!! Nah, that's not possible but I do love it. It motivates me to get a minimum of 10,000 steps in daily but of course, you get to set your own goal. You can also arrange the display any way you like, so I put the time, my steps and heart rate on the first screen. I love that it tells you who is texting you at a glance. It's easy to use, and once I got used to wearing a watch again, fits nicely and is comfortable on my wrist. It does have one minor flaw in my opinion. The strap closure piece is awkward and difficult to move into the various slots. I always feel like it's going to break but it has been about 2 months and it seems to be holding up well.

My wife loves it! Bought this for my wife for Valentine's Day (at her request). She really likes it. Price was good - I think it was cheaper than any big box stores. She was surprised that it tracks her sleep too. Connects to her iPhone via bluetooth and relays all the info so she can look at it. Her mom's friend got an off-brand fitness tracker and my wife had to go help her connect it and download stuff - she said it was a pain in the butt. This has very easy user interface and OK connectivity - I say only "OK" because it took a couple tries before it would latch on to her iPhone.

Addcited to my FitReact After just 2 1/2 weeks, I am addicted to my Fitbit. I have said good bye to my sedentary lifestyle and am now walking a minimum of 10k steps/day. I also have increased my water intake to 50 oz/day.

Already making progress :) The tracker does hold me accountable. The ability to track my steps, calories burned, time active, floors climbed and miles covered, make me want to move and workout. I can look back at my stats and see how I am progressing.
