A stepped on my gopro hero 3+ at the recording but has always posed problems for the transfer. Whenever some files that remain on the sidelines and refuse to copy the card on my PC. Seen with Amazon telling me to do with sandisk. Seen with sandisk which accepts the return of the card in the Czech Republic ... was ... my expenses and monitoring .. already exorbitant price, not really no choice with gopro hd and more guarantee a return at our expense .. .. it's even too much for a clear piece of plastic manufactured in china ..
