Long Lasting Battery5 Posted by: from: on The battery lasts a long time .... 2 plus weeks at a time. Also charges fully within 10 minutes. Has everything I need in one small contraption.

Just what I wanted4 Posted by: from: on I like this because it has all the functions I need plus access to the app but I still get to wear my nicer watches.

Not a fan2 Posted by: from: on Seems inaccurate based on iPhone counts. Not a bad system to get you moving but super simplistic.

Fitbit's Crown Jewel5 Posted by: from: on The Fitbit One was the first product I owned from Fitbit. There are now many different types of fitness trackers on the market, but none quite as community driven as Fitbit is. The application is very well designed, and allows for communication interface with friends, family, and other Fitbit users. I do not feel that I need to cover the functions as the product description accurately reflects the uses of the device. As a professional, I did not want a plastic/rubber looking device on my wrist. The Fitbit One allows me to wear my device, discretely. I have never had problems with the device, and Fitbit's customer service is always top notch. At the $99 MSRP price point, the Fitbit One is pricey. However, I would make this purchase again, and I would recommend it to a friend and buy it as a gift.

Does the job!4 Posted by: from: on We bought this for our 7 yr old to keep him reminded about staying active. It has done that and more, as we're all involved in hitting our daily step goals.

Great activity tracker5 Posted by: from: on Bought this for my wife who's original fitbit (same style) finally broke after several years of use. She loves it and uses it with her phone and apps. Says it is very accurate.
