They seem to function fine (I ordered two), however they are filthy and beat up. They were listed as like new condition and they are poor at best. There are stains, gouges, and dirt all over them. There’s also dirt in the ports and in the keys. They did come with chargers though so that’s cool.(Update 03/09)I contacted the company and they offered to replace them or provide a partial refund. I went the partial refund route because I really didn’t want to have to go through the hassle of returning them and the possibility of another set of damaged ones. But they issued the partial refund right away.
