I purchased two of these computers, one for my son and then one for myself. At the time of this review, I've had them for exactly two months. The first one took 7 days to my door, the second took 9 days, both were packed well.  One had damage to the box, the Styrofoam inside was crushed to little pieces on one corner and there was a dent on the computer case (no fault of the seller) and the second PC had no damage to box but a small dent in computer case.Both worked great from the start with the exception of the wifi dongle that is included.  Wifi was intermittent and slow while other PCs in the same room even 2.4Ghz built into my laptop worked better than the included dongles.  Do yourself a favor and order a new wifi adapter.  I ordered a 802.11ac (5Ghz only) adapter for each and my wifi speed increased x 10 and was rock solid.One thing that concerned me buying a refurb PC was the licensing of Windows 10, but it was easy to register the Win 10 Pro to my Microsoft account which was very nice.  The included instructions recommended doing so.  The instructions were decent, easy to understand.We are both very happy with these computers, the performance has exceeded our expectations.  Aside from the wifi dongle, we have not had a single negative experience.  I have loaded up a lot of software (Microsoft 365, MS Sql Server, MS Visual Studio 2015 and more) and it runs great.  Every time I re-boot, I'm surprised by how quickly it comes back up.  My computer has been on since the day I received it.I thought about deducting 1 star for the wifi dongle but I knew up front at time of purchase that it was a dongle so my expectations were pretty low, so I did not deduct.I got more than I was expecting from a refurbished computer and would recommend purchasing from this seller.Having 90 days to return it is nice to!1 year later, both PC's running great!  Still 5 stars!
