Bought one of these because hey, MS Pro Duos are expensive. >.>
This worked fine - for a week and a half. Then, suddenly, my PSP stopped recognising it. I never touched it or removed it, played it one day, fine, played it the next day, it's telling me there's nothing inserted in the MS slot and the light just keeps flashing at me.
Have tried formatting it, but nothing.
The card also was not the one shown in the picture - it was similar, but not the same. It didn't have "PhotoFast" written on it, and the micro SD card slots were white instead of black, and a different shape. After checking the link in another review I have to conclude that this is a fake one, which is probably why it doesn't work.
Also, the packaging was awful. It was just sent loose in a regular envelope, I'm surprised it didn't snap in half during transit as it's very flimsy. So obviously it wasn't even new (or the right product!) as the card is supposed to come packaged in a box.
I am trying another card to see if I get better results, as I really WOULD like to find an alternative to the incredibly overpriced Pro Duos. I'll update with whether it's any better and whether I'm actually sent the proper adapter. At least this was cheap so I didn't lose much.
