This copier is fast and efficient, I was able to copy 7 new SD cards in less than two minutes, I had to call customer service to copy my first few parts, they were friendly and helpful. it was my SD master, which wasn't good. The only negative thing I can say about this device is the fan noise. All about the high quality box design. but the fan is a bit noisy as it is in the corner of the desktop. In a store environment I don't see any problems with noise.
