This Samsung Chromebook arrived in a tattered box for a Lenovo Chromebook. Upon unboxing, I found they boxed it up with NO POWER ADAPTER OR PLUG-IN WALL SOCKET ADAPTER. Amazon issued me a credit that allowed me to get a power supply and cable locally. Once I plugged it in, I discovered it could NOT READ AN SD CARD. Essentially, the port was not functioning. It's going back as a return. I ran several apps and found the machine hung, as in froze. As for cosmetics, the screen had lots of greasy smudges on it, and the outer case was grimey and needed wiping down. All in all, I've received better stuff from eBay than this piece of nonsense. I think rather than sell these as recertificied, it would be more accurate to call them RECYCLED. It appeared as though the thing had merely been reboxed and sent back out. I neither recommend any recertified anything from this merchant or Amazon. This was junk in a box.
