Negative Positive
Title: not for anyone on the go
Review: The battery life is awful. The first one I bought lasted about 2.5 hours, even though I was very careful to follow the instructions because I'd heard that it could be a problem. I returned it before the first 30 days were up and got a new one. It seemed to be much better at around 5 hours of use, but has since declined to around 4.The controls are also incredibly difficult to use with any accuracy. I thought I would get used to spinning the wheel, but I continue to have trouble selecting exactly what I want if I am walking or doing anything other than sitting at my desk.I had two Rio sports before this one and thought I'd be better off with more capacity but it's turned out to be a great disappointment.
