This is an exceptional value- works great right out of the package (which is important because you don't get any instruction sheet). I bought it because my previous reader wouldn't handle the 2GB cards I bought (or SDHC cards, though I don't have any devices that accept these yet).
Downside: it doesn't plug directly into the frontside USB ports because my Dell didn't leave enough flat space below the ports. A thoughtful redesign might have solved this. It does fit in the ports that come with the flat screen monitor I have but green "activity light" then faces the wrong way (tells you when the card is being accessed and you shouldn't remove the card). Also it would be nice to have an indicator showing which way to insert the card.
Still, for this price it is a bargain.
