Two of my 3D printers use Micro SD cards and one uses Mini. I upload files to SD cards all the time and the adapters I had were too small to keep track of and difficult to use. It stands beautifully on my desk and is always ready to use. Also, the Safely Remove Hardware tool doesn't show up at all, so I can insert and remove cards without bothering. Good price and so far reliable product.
