I could not keep it because it is 12.5mm and I needed a 9mm, saying that it is very well finished, add to the AC adapter to turn his great internal CD drive externally, this is the ultimate combo. If you need an adapter 12.5mm, you can go there with eyes closed, saying that for a piece of metal, and despite the degree of finish almost perfect, the price is a little high, the fall by 5 ~ 10 would be enormous and would make it a true reference
