Bought two of these as potential gifts - attempted to load photos onto them, and they didn't show up on my Mac.
The 'manuals' were fairly poor (there are some clear errors in the typesetting which looks like they've been quickly translated). I'm not sure whether they're meant to work with Apple Macs, and the seller didn't provide a straight answer when I asked the question.
Currently awaiting a refund after sending them back. Overall poor, not a good start to Christmas gift buying. If you are buying as a gift try before you wrap!
