If I know I’m buying junk just because it’s cheap (bad idea, because it reinforces that incentive for companies to sell even more junk), I’d expect it to break, and rip it apart for parts like a dead Borg. Or if there’s fraud involved (“high quality like XYZ!”), I might chase after them just for spite.

A legit dud, sorry, but whatever warranty the seller makes it out to be, I expect them to make good, or expect a public shaming.
