The case is perfect for a 12.7mm DVD drive. It really is processed very good for the price and even attenuates the drive noise enormous. I can operate with only one USB cable to my laptop, but a second is included, which can be inserted into the socket, if the USB port does not have enough "juice" for it. Commissioning is simple. The drive is, however, not pushed into the housing, but the housing must first be pushed carefully (because there is a danger that, I call once Cancel "pin") are, so you have two halves, then the drive is put into it, connect the SATA to USB adapter to the drive and associated pushed the housing again. The author, who wrote the only bad review wanted, apparently simply push its drives, but this does not work, because it has to be pushed in two halves.
