I normally don't write reviews, however, I felt this deserved one. I purchased the HP EliteDesk 800 G2 Mini Business PC from the seller. What I received was the HP EliteDesk 800 G2 SFF which is much larger. I work in the Information Technology Industry dealing with programming, software, and hardware which makes me think that I have at least a little credibility when dealing with PCs and knowing what should and should not be.The purpose of this system did not require high-end hardware and I was fine with the system being "Renewed" as I can deal with most problems that arise. What was a problem is that the item I received was not what I ordered, that and it was pretty beat up making me question the "Renewal" process. The top cover could not even be removed as the latching mechanism was damaged.So, I started the communication process with the seller. At first, they were pretty responsive. We exchanged a few communications with the last one requesting photos of the PC I received. At this point, I was fairly confident that they were going to correct their mistake. I submitted the photos as requested and then nothing. No response, other than the automated response confirming that they received my submission. Over the course of several days, I sent messages requesting a status update, however, I did not receive a response to those either.I should have known better, as did read "Customer Service's" review citing the same exact problem, but I was thinking that maybe this was an isolated incident. Apparently not.This seller has many positive reviews, but I urge you to use caution when it comes to this product. Purchase at your own risk.
