This card works perfectly. Its only flaw on paper tranfer speed a little lente.Sinon not hold especially not account previous comment. This comment is stupid. It's not the card that is incompatible with the R4, but inverse.Cette card does not work with because the r4 r4 does not accept more than 2 gigabytes card. Before buying a product, we get information on compatibility with the unit that we will utiliser.les SDHC cards are recent, so make sure your laptop or other device is compatible.
