I would honestly suggest avoiding this card. It may only be $6.99, but it doesn't have official support for Wood R4 nor do we know how long it will have any support. I suggest if you want a cheap flashcard that works, go with original R4 (now 1.1 clone) it doesn't support SDHC or 3DS/DSi, but it's better than this card. If you want a budget 3DS/DSi card go with the R4i Gold (url on card: http://r4ids.cn/). Otherwise I suggest avoiding this card.
