TBH I've not had any issues, I've sold them a couple of used GPUs that weren't in the original boxes, and a used G29 wheel that was in the box but kinda loose without any quibbles. Although the GPUs were quite scarce at the time so they were probably desperate to get hold of stock as would be able to resell quickly. I did also buy a ridiculously expensive GPU from them (£775 for second hand!) that I justified to myself my having got a 'good' price for the old stuff I was selling them.
