    Great tool to help get in shape...

    I've had my Fitbit for almost four months. I love my Fitbit. This is a great tool to help with losing weight and getting back in shape. It has pushed me to stay more active and competing with friends is motivating and fun. Fitbit has also been great at helping me keep track of what I'm eating. My biggest issue was that even the large wrist strap was on the small side. A couple emails to Fitbit customer support and they sent me a free XL wrist strap.

    Great Product

    I was a little worried on the mixed reviews on the Fitbit Flex. I currently own the Fitbit One and loved it. I haven't had the issues with the clasp being difficult on the band nor the accuracy. I did P90X Kempo which has a lot of steps and arm movements. I wore my Fitbit One to measure against and it is was only 100 steps off, so fairly accurate. Battery life seems good so far. It tracks when I wake up during sleep more accurately than the Fitbit One. a.The only issues are: it doesn't log stairs like the Fitbit One, nor does it have a display on the device itself, but other than that I love it.

    Better than expected

    Don't listen to the negative reviews. Having owned the Nike Fuelband, Fitbit Ultra, and MotoActv I can say the Fitbit Flex is my favorite device. Comfort and accuracy is what's important to me and Fitbit does it better than anyone else. I really like the stats and the ease at which it syncs to my iPhone/iPad. I know, it has a limited display but that might be the reason this thing is so lightweight and comfortable to wear. The 5 LED lights are just enough to communicate to me how my day is going. And the tactile response when I complete my goal is awesome. Fitbit tracks stats like no other device I've owned. And their website and apps are very nice. I highly recommend this device if you enjoy working out and looking at the stats over time.

    Great Device for Curious People

    The Flex is a great device for those people curious as to how much they walk in a day and how they sleep. It's also a perfect device for those who want to set goals and motivate themselves to push for better. Will it be 100% accurate? No. Of course not. I am an avid air drummer so the Flex will sometimes register some of my amazing drum skills as steps, but all in all it gives a pretty good estimate on the amount of movement I've done. I was amazed by the sleep tracker as well. In the times that I've tested the sleep mode it has been pretty accurate. The silent alarm is probably my favorite feature. I didn't even think I'd be concerned with such a thing but I have quit using my phone alarm completely and depend solely on the silent alarm built into the Flex because of how effective it is at waking me up. I'm very impressed. I haven't had issues with the set up or their customer service. Things are working exactly as advertised. I'm happy.
