Hi, Please could you help me decide which electric razor to buy for my 13 year old son? He hit puberty early (Year 6) and has been shaving for a couple of years using a disposable razor. He would now like to try an electric razor. We don't have an electric socket in the bathroom so it will need to be cordless/rechargeable/battery operated. I don't want to spend a fortune as he's prone to dropping/breaking things! Any recommendations gratefully received. Many thanks x
