Amazing device for SDHC. Since may PCs or older card readers support only SD, this was a super easy and inexpensive solution. Since SDHC cards are increasing in capacity you can also use this device as a flash drive. I used primarily for my camera with Micro SDHC card. Slip it into an adapter (not supplied), then into this device, plug in to USB port, download pics and done. Lot less wear and tear on the camera and battery. Can't beat it for the price.
