The disc comes in perfectly, no friction (unless the tower is not perfectly placed flat), the door locks fine means a "click".
Only negative, the S-ATA power connector to a game, it may just my connector, but nothing off the power.
The door is plastic, not open like a nag, or I would not give much to plastic, but care is taken and it is not open every day.
I intend to buy two like that, it's a great product, do not hesitate.
