So I almost never write reviews yes (sorry). But here it is a time attached. The plate came within 24 hours. Sensational. Installation in my Mac Bokk 13 "the end of 2008 without any problems. Very fast and reliable. The data were rüberkopiert with Carbon Copy Cloner from an external. Wait 2 hours. Done. And according to the plate really is not. If you overworked, sounds to a light "work". TOP and highly recommended !!!
