For a long time I wanted to try a camera like that but do not go pro interessted me. I waited a little (I was myself a ghost drift stop) and I saw the new sony. Very compact, very light. I find it enormously has advantages over go pro that are a little cameras "apple" !! very fashionable, super quality but in my opinion are now outdated by the competition. Watch the sony: gps, stabilizer, control the wrist, waterproof without cabinet. For me there is no comparison. Attention on the sd card, take a sdxc (not like me a SDHC, thank you amazon for the management of Reimbursement was my mistake) to shoot in the highest quality. In short, completely conquered by this small camera. I will buy accessories and strongly qq I try skiing ca. FYI, I had taken with promo, less expensive and more accessory Free sony (perch, phew!)
