Over the years, I have bought quite a few electronic “refurbs” and saved a bundle in the process. Only had one failure - and got a refund on that one.
I was in Fry’s one time and they had a massive end cap of refurbed Iomega zip drives (this just before the onset of USB sticks). I figured there was no way that that many units could be refurbs and that it was more likely excess stock dumped in a way that wouldn’t permanently reduce the price of the items.
I’ve seen that lately with video players and recorders - and some flat screen monitors.
