I have no complaints about this computer. Light weight and slim. Came in excellence condition only one tiny mark on the bottom which you can't see unless you do a close examination of my Mac. all the keys are working no stratches on the screen. Hope my lil reveiw helps. after look at reveiws of computers i narrow it down to 2 and end of choosing this one. oh and it power on and off with no problem and holds a charge for a exceeded amount of time.
