DMS 6-in-1 USB 2.0 High Speed Memory Card Reader Writer for SD SDHC MiniSD MiniSDHC MMC rsMMC

Ordered two Sandisk 4GB MicroSDHC memory cards with SD adapters. Digital Media Source (the store where the memory card and adapter came from) offered this card reader free with the purchase. One of the readers worked perfectly, the other gives an error message whenever a memory card or combo card is inserted in the reader. Unfortunately, I spent a couple of hours trying to get the bad one to work before I finally tried the other reader and found it worked.Buy DMS 6-in-1 USB 2.0 High Speed Memory Card Reader Writer for SD SDHC MiniSD MiniSDHC MMC rsMMC!
