The add states that "Amazon Renewed products will be clean and will have minimal to no signs of wear or visible cosmetic imperfections when held at an arm’s length." This was not the case with my purchase: not even close!! When I removed the shrink wrap, there were numerous black specs of grimy, oily-like grit inside and on the outer case of the machine. Each time I picked it up I got this oily, grimy substance on my hands and it came off on my kitchen countertop and was extremely difficult to remove. I removed the side panel and found the same oily, gritty, black substance all inside. It looked like smoke or fire damage and there were particles of brown dirt all around the housing of one of the fans. The other fan had that same oily build-up on the fan blades and several of the wires inside had a similar grimy covering on them. The entire back panel of the computer was grimy and could not be cleaned. This grit was even inside the the USB and Display and ethernet ports! I paid to get what was advertised and this was not as advertised. I could not get past the disgusting look and "feel" of the machine.  I had to try it out, though, just to see if it even worked. While It did work, I was not about to accept it in the poor, unclean, dirty condition in which it was shipped. Within 72 hours of its arrival, I processed a return to Amazon and will be delivering it to the shipper tomorrow.  Skytech USA LLC is the Microsoft Authorized Refurbisher (MAR) on this machine. I hope this was an aberration because if this is the way all of their machines are shipped, they should have their MAR's certification revoked.  The condition was wholly unacceptable.
