    I absolutely love my FitBit Flex - it's helped me lose 50 lbs in the last year by tracking my steps/miles, my food & sleep. I'm addicted to getting my 10K steps in and had to replace my old one my dog chewed up (YES this really happened) with the new pink one. I love it!

    After being gifted a Flex, I bought this one for my mother. She immediately signed up online, we created a set of family connections and have been good-naturedly competing ever since. The rare, but occasional loss in the weekly step count is absolutely worth knowing that my mother, brother, sister-in-law and others are purposely exercising for the first time in years!

    Everything about the device has been very good except the accuracy of the step counter. We have 2 fitbits in our home and they definitely do NOT record the same information even when used side by side. Very frustrating for one of us to reach our goal way before the other, even when walking in lockstep together.

    NOT A Great Product!

    The sleep tracker/silent alarm function was a huge selling point for me with this device. I'm a little disappointed that the sleep tracking/alarm has no detailed analysis of the quality of your sleep, like the one I have on y iPhone; but instead it only tells you when you slept and when you got up in the night. I realize that sleep tracking (deep sleep vs. light sleep) is pseudoscience, but it would be a nice data point. The alarm will just go off when you set it, so don't expect it to wake you up when you're more "rested" like some phone apps. The silent alarm is really not very silent at all. If you have your wristband up against anything besides your wrist it will vibrate the hell out of it.

    Excellent device to track daily activity and take accountability for not being lazy. I've been using for a month and have already lost 6 lbs. I've been able to accomplish the weight loss by simply being more active in my daily life, with a personal goal of 10,000 daily steps. When I first started I wanted to establish a baseline, working in an office setting and coming home to melt into my couch to watch tv I quickly learned I was only averaging 4k daily steps which is nothing. I now doing everything possible to hit my daily goal of 10k and quite often go to bed well over 13k which equates to over 6 miles. If you've been looking to boost your fitness this device will definitely help push you to be more active.

    I first bought the Fitbit HR - great but too bulky for a small arm. I really like the Flex that I traded the HR in for. It fits my arm better and has most all of the information of the HR except for Heart Rate and Steps. I do miss reading the information on the instrument but I knew going into it I was going to have to use my IPhone. Overall, the Flex is exactly as it was promoted. Very Satisfied.

    the fitbit is a very good tracking device for fitness results. you wear it on your wrist as a bracelet. the wireless software easily summarizes your results on any device you may have. a bit pricey though.

    My fit bit battery lasts for 3 days about. Tracks every step, I've also programmed it to track my steps from my phone too which is a nice option. My sleep tracker is my favorite part of the item.
