Updated Rating - Stallion Tek replaced my original purchase within a week. The new system was in a little bit rougher shape than the first one, more scratches and such, but not at all bad. When I received it, I heard something rattling inside, and when I opened the case, I found the plastic piece that covers the power supply had a broken part, but it does not affect the system at all. The system booted right up and is working well. They did not include a wireless adapter with the system, but when I let them know, they over-nighted one to me. I'm happy with my purchase, and very happy with their support people. I would buy from this company again. I was pretty encouraged by the other reviewers of this product, so I decided to buy it, even though it was refurbished. I was skeptical when it arrived; it was marketed as a Core i5 w/Windows 10, but it still had the Core i3 and Windows 7 labels on the case. Nevertheless, they had upgraded it to those specs, so I was happy. However, this computer would not boot at all out of the box. Tech support tried to help me, even sending links to load the ISO files to format the hard drive, but nothing worked.  I am returning it today, hopefully they will replace it with one that works and that meets the specs. We'll see. If the computer had booted up, I would have given this product 4 or 5 stars--it was in good shape and had no other deficiencies that mattered to me. Also, tech support was helpful, and I appreciate that.  I am happy with the company's service.
