I was nervous buying used from a non-Apple seller, but it has been good so far. I’ve had the computer for about 3 months and the only thing I’ve noticed is that the speaker isn’t very loud on some videos. Some, not all. Other than that it’s great- battery was at 97% when I got it. It did come in an unremarkable box with a cheesy generic adapter, but what are you gonna do. For the price I’m definitely satisfied and am glad I got this one and not the Air. The screen is fabulous, doesn’t hurt my eyes as much and is great for photo editing. It’s a yes for me.
