The case is made with excellent quality. The drive is attached to the board, then the coupling is placed in the lower half of the case. Next, the lid, with a slight displacement, fits into the grooves of the lower half and moves to its place, then fixed with screws. On the lower half, in the area of the connector, there is a pin-stop so that the plug does not push the connectors inside. Package as specified in the lot. The drive I have is old, reads not everything and not always. Therefore, it is difficult to evaluate the product for the electronic part.
