Negative Positive
Title: Beware: it may not be compatible
Review: I purchased this item to use with a Yamaha QY100. The device was not able to format or read the card. I was able to format and erase the card in my card reader, so it is not defective in that sense, however I cannot use it.Update January 2013: Bought a new card, sealed in the original package, on ebay. This card worked perfectly. I think the generic cards sold on amazon are sub-standard or defective.
Is the review positive or negative?
