Here is a key not too bad, the highlight are its high capacity and a transfer rate more than reasonable (even very good) However the key bombed early in the transfer, and regresses a bit settings (normal, like my old one) but in the end, the transfer bar locks, yet it is finished, but all the time it subsequently falls a win before that time . Indeed, the transfer was completed on time also felt so be aware wait between 45s and 1min before the transfer is properly completed. For a film with a 700MB transfer 100MB / s should therefore 7s. but not all it takes exactly 42s. who knows why. In addition some transfer fair with the supplied software (turbo thing ..) is indeed to choose between normal or turbo speed but movies transferred my keys are not recognized because they were damaged. So the key is very unstable I find with this app. So I use it alone and malgrès concern described in the beginning its still a good stuff. Little also note: It heats enormously careful fingers when you removed the aluminum hull because malgrès well it a little hard to broadcast its own heat.
