I purchased a gowearfit in Feb. I had been on a plateau for several months with my lapband. I wear it all the time, except for the shower. It has helped me to get off my plateau and to correctly calculate how many calories I am burning when exercising and how well I am NOT sleeping.
One of the down sides to any of Body Media's devices, I ride horses and it calculates the horse steps as my own. I had to set the step total significantly higher than normal to account for it.
The food database is not as complete as I would like. Many of the organic healthy items are not there and I must add the nutritional information; i.e. Costco's whey Protein isolate, Barlean's Fish Oil Supplement, etc.
On the upside, anytime I have had a question, Body Media is quick to respond. When I had the velcro on an armband come apart, they quickly sent me another one. The customer service is second to none.
I also completed a dunk tank test to determine my lean muscle mass and RMR (Body Fat Test - Home). I am within 20/25 lbs of goal and am currently using my gowearfit to correctly determine calorie intake based upon calorie burn to get those last few off. I am at 7 CCs in my band.
Forgot to add: I am a Project/Program Manager consultant and wear my armband to the client's office. Some people ask and I just explain what it is, some never seem to notice. I often forget I have it on.
