    Perfect Activity Tracker for Me

    I have been using my Fitbit Flex for over a month now, and I couldn't be happier with it. It took a couple months of online stalking before I found one in stock, which was a little discouraging. This was worth the trouble. I initially purchased my Flex to try to get a better idea of how much I was moving in a day - I work on my feet all day, and other pedometers I have tried weren't able to track all the movements I was making. The Fitbit Flex gives me a great overall look at my movement, and tracking my progress on the device and on the website is fun. The sleep tracking is really interesting, too. I also like the other features on the website; you can log as little or as much as you'd like - food, activities, sleep, journaling, heart rate, blood pressure, glucose.

    If your looking for a tracking this is a great product. My whole family has one and we challenge each other to step up every day. It's water proof so you don't have to worry about taking it off unless your charging it. Charging it can be tricky at times as the doggle doesn't snap in right sometimes. Other than that pretty easy to use.

    Just snap it on and track away. Helps me keep on track with my activity and motivates me to take those extra steps. It was easy to set up with my Mac and my iPad. Synching is simple though when another Fitbit is in the household, can't get too close.

    Nice to track steps and calories in one place. Bot to train for a 5 k. Keeps me aware of activity or lack of activity. Provides a sense of accomplishment when reaching 10 thousand steps. I don't fee I wast my money. Running walking steps. Tracks it all

    I like how it keeps track of the number of steps I take. I was also surprised to see how much real sleep I was getting at night. Would be nice if they developed a version that also picks up heart rate. All in all a good product. I use it and I like it.

    Overall it is a fair activity and alright sleep tracker. Easy to use for the most part but it will randomly slip into sleep mode without notice. Steps it where this shines. I cycle for 2-6 hours a day and in my log files it barely shows activity. I didn't expect it to be accurate in regards to cycling but a little movement should be detected; I ride a fixed gear bike where my legs are always in motion when the bike is moving. App allows me to manually place in these activities, so it balances out as long as you keep the app up to date. For me the app needs some work though it does cover many areas and can be leveraged to build health related goals. Overall, not a bad tracker with decent application supporting it.
