User Reviews about Athenatech cr-52in1-b Card Reader Black

It probably works well if you have the proper interface. It has a plug with 4 pin holes over 5. I didn't have such an interface on my motherboard (Dell Dimension 8300)and couldn't find a USB expansion card that did so I returned it to Amazon.
I wound replacing my floppy drive with an Ultra combination floppy and media drive(link below) and a USB expansion card with a 4 pin interfce because DEll omitted to provide a 4 pin USB interface on my motherboardInternal Media Drive Black. -- Rather odd interface

It's good -- rpr
