I can see the MF-515B - Storage bay adapter 13.3 cm = 5.25 inch to 8.9 cm = 3.5 inches recommend. Since the compact design made of aluminum, very stable and easily is, all corners and edges are rounded off and freed from the clean degree. The installation of the Samsung High Speed All in 1 Multi Card Reader into the adapter MF-515B was no problem and in time great effort. The screws supplied with 8 ranged for the adapter and Multicard Reader (here was unfortunately saved on the screws). Intermediate adapter slot and card reader is around 1 to 2mm air, which no longer noticeable after installation. All in all, the quality is impressive. TOP!
