I bought this as used from the Amazon Warehouse. It was described as like new, and the only issue was that the packaging was damaged, but the laptop was fine. This however, was not the case. As soon as I started it up, I noticed that the mouse pad was acting weird, and wasn't responding right when I would touch it. After exploring the computer more (and restarting it multiple times) I also discovered that the camera didn't work either. Thankfully, I contacted Samsung and the laptop was still under warranty, so they had me ship it in to get it fixed. (I'm waiting to get it back)Moral of the story: be careful when you're buying used. I was lucky enough that everything worked out in the end for me, but just don't want anyone else making the same mistake.
