I had what turned out to be a minor issue with the DVR not working properly. I say minor because the seller handled the issue rather quickly and followed thru with me to assure the issue was resolved. The one year warranty was a plus when I bought this PC. It is and does what they claimed. However, later, they made it very hard to contact them by phone, email, etc. They refused to reply to a question, not a solution, so I dropped two stars.
