I bought this add-on for my husband's cpu because he has a number of floppies that he still uses. Now that the installation is complete, I wish I had bought the USB floppy drive instead. The unit went in fine and works fine so far, but here's the problem. The Parts List said it came with 3 belts for the various size machines it is intended to fit. But mine came with only one belt--very short. Luckily, I had an old machine to cannabilize for parts, otherwise it would have been back in the mail for a replacement unit, etc. I can only hope that I was not sold a used/returned item. Buyer beware.
