    love this thing. super easy to use and track. battery lasts almost a week with 24/7 wear and even emails you when its low. My only gripe is that the sleep mode activation could be better. i do get false positives when driving on bumpy roads and it's still hard to activate regularly with certainty. (it always takes a few tries)

    I work long hours/days and was not really keeping track of my activity or diet so after realizing that I was waking up every day feeling terrible I decided to do something about it. After doing my homework it came down to two... Fitbit Flex and Jawbone Up. To be honest I liked both but the deciding factors for me were this... 1. Fitbit Flex syncs via Bluetooth (Jawbone Up does not) 2. Fitbit Flex has a mobile app as well as a web interface (Jawbone Up has mobile app only) 3. Fitbit Flex $99 (Jawbone Up $129) The calorie counting is also very easy to use. I have been using it religiously and have dropped 10lbs in 5 weeks by just hitting my daily step goals and following Fitbit's recommended daily calorie intake and nothing else.

    My mom got this as a gift and she loves the badges you can get and that it gives you sudjustions on how to sleep but the 4 stars is because I see her having to take the thing apart to charge it rather then just plug it in.
