Very convenient card reader: really very portable, no need external power, read several card size (SD, Micro SD ... for now I have never had a problem with no card), light, n 'not affect the transfer speed (fast USB cable) ....
Anyway its done very well the job and the price is reasonable, I recommend it.
Ps: it takes a little support to properly put the card at the beginning can be scary but it is normal and does not damage any of the cards.
