This drive does perfectly what is asked, ie read the cards "micro SD" and "Micro SDHC" (not to be confused with SD cards that are much larger). No need driver, plug and it is recognized immediately. No need either software. Once inserted the card, it goes into the workstation ("Computer" on Vista) and double-click on the new removable drive letter that was created. Its size is tiny (about 1.2cm long 2.5cm wide) but as you can see from the photo, there is a mini clip which allows to hang it for example on a key ring, a choker , or other. The only downside to this type of key is that it must be careful not to lose it (given the size and color black, good luck to find it).
