Great product, especially the price you cannot complain!
Bought this card for use with my HTC Desire mobile, at first I had a rare problem with the phone not recognising the card and refusing to mount it but then I formatted the card again using a small tool called "SDFormatter" then it behaved again. - Took the best part of a day to figure that out though.
Besides my rare case of the problem above, that should not deter you from buying a fantastic problem at great value.
