It's not the smallest USB Device going, but it is one of the best. Able to ready all the pupular types of cards, including MicroSD WITHOUT using a converter! The device is a dream. The case opens up both sides to reveal slots for memory cards to fit in, plug yours in, close it up and then plug the unit into an spare USB port and bingo - simple as that!
Mine is connected through a 4-port unpowered USB hub (as all my USB ports are at the back on my PC and the hub gives me easy access to four more), fast read/write speeds. Vista Ultimate had no problem reading my 4GB MicroSD card from my PDA. Even when connected with my standard 8Gb usb Memory stick, the device worked like a dream copying direct from MicroSD to USB Stick.
If you want a simple, easy Memory card reader (and a portable one at that) you can do a LOT worse than get this. It is a winner in terms of price, speed, looks & fuctionality. You will NOT BE DISAPOINTED!!!
