I was looking for a card reader to mod into a nifty drive and I saw this one on DX.com. Ordered on 4/12/2013, received it in the mail today. The card quality is good. Transfer rate is good. The bad things are: the microSD area doesn't go inside when plugged into the rMBP, can't connect the USB end to the rMBP because it's too short (works fine on my Dell laptop's USB 3.0 ports). Still, it's a damn nice card reader. I'll use this combo card reader as the replacement for my full side SD adapter and microSD USB reader.
