The card has the product picture Class 4 delivered, but was only Class 2. This would have been to get over, because the speed is still intact (Write: 5.5MB / s, read: 14 MB / s). Much more annoying is the fact that the SD card adapter (counterclockwise product image also not from SanDisk) is too wide or thick and does not fit into the slot of various card readers. In addition, also the write protection does not lock. The adapter is simply scrap.
