It's not that you will never have a problem with your order, it's how you are treated when there is a problem that counts. I ordered this reconditioned PC because I needed one to control me Computerized router (CNC) in my shop.Upon arrival, I noticed the retainer that holds the cards in placed was cracked. I contacted the seller and after identifying which part was needed gave me the option to exchange PC or await the part. I had already installed lots of software, so I opted for the part. It arrived quickly a solved the problem.Several days later, I went to move PC to it's permanent location and noticed I had to re-enter date and time. I contacted seller again and they believed problem was in Windows 10 itself. Having been a PC repairman in the old days, I knew the problem was actually the battery on the motherboard. I replaced the battery and everything worked fine. I did not blame the seller as the battery can fail at anytime.The seller contacted me again and asked if everything was okay. I told them the battery needed replaced. I didn't ask them to, but they sent me a new battery anyway.I have 10 hard drives running off this PC at the same time. 2 inside the PC, 4 from the USB ports on the front of the PC, and 4 on an add on card I installed in the back of the PC. Everything is very quiet and no problems to speak of. this PC appears to be quite the workhorse!It is obvious to me they want every customer to be completely satisfied...I sure am. I was very impressed on how well the PC was reconditioned. To look at it, you would swear it was brand new. Not a speck of dust anywhere. I would not hesitate to buy from this seller again. Very pleased with both product & service.
