For a long time I sought a USB3 card reader in order to transfer my pictures to my PC and my NAS. I'm really happy with this player. In fact, no need to force to put the cards and the transfer speed is really fast. As owner of 32 cards go, I really see the difference in the transfer time compared to my old memory card reader ... I do not give full marks for that player does not support all card formats :( (not XD cards)
