I purchased 3 of these computers for my children to do their normal online schooling. The outer appearance looks okay, but 2 out of the 3 don't hold their charge and have to be plugged into a power source at all times. Also on two of my children's laptops, their online schooling videos in every subject do not play correctly, they are very choppy and slow. I realize these are refurbished, but I was hoping to get at least something that would hold its charge and help with their schooling, better than the Microsoft laptops they previously used. The problem is my family lives overseas and I purchased on a visit we made a month ago to the U.S.A. Now I can't return due to being in another country. So if your looking for a used reliable Mac, I would not recommend these laptops.
