Rated 5 out of 5 by awesome! Love this thing! I work in college athletics and my schedule can be crazy, the FItbit has allowed me to make it through preseason healthy and ready to tackle the school year. I sleep better, and wake easier with the vibration, instead of being jolted from my sleep by a loud alarm. With the food tracker I am making sure that I choosing healthy food...even while traveling with a team. It's exciting to see my progress each day and keeps me focused on getting my workouts in because I want to reach those 10,000 steps! Love when the fitbit vibrates alerting me to reaching a goal...and it's only 1/2 way through my day :) 09/03/2014
Rated 5 out of 5 by I love my fitbit. I asked my husband for a fitbit on my birthday. I have been wanting one for so long. I was so excited when Kohl's started selling them. After I received my fitbit it only took a few minutes to set us. I was having trouble ordering it on the kiosh so a store employee called the online place and a very nice young man took all of my information as we were going on vacation and I wanted to send my fitbit to my daughters house. When I arrived at her house my fitbit was already there. Thank you Kohl's I love your store and the people. Several of the employees in the store I know on a first name basis. The manager is awesome. They do so much for our local community. Thank you all 06/12/2014
Rated 3 out of 5 by Broke within 1year of purchase The area that holds the "brains" split open and the device would no longer accept a charge. This was after almost one year of daily but gentle use. Device never stayed on when I slept. Best thing, however, is that kohls accepted as a return with no questions asked. Kudos to Kohl's!! 06/26/2015
Rated 4 out of 5 by Great product I like this. I was afraid I wouldn't wear a clip-on style. The bracelet is easier and blends in with everyday wear. The band is difficult to fasten alone. Especially if you have severe arthritis in your hands like i do. But once its on it seems to stay put. Its waterproof. The battery lasts for several days before you have to recharge it. The blinking light system is difficult to figure out. I synced it with my phone then log in online. I like that it keeps up with not only my steps but my sleep cycle (sensitive mode). I'm a terrible sleeper and now i see why. 02/13/2015
