I was too. If you list it as "spares/repair only because no returns on XYZ" then it doesn't affect final value. I use this when selling vintage equipment because while fit for purpose at the point of sale it could blow up a week down the line with a new issue (as any second hand goods) or the buyer could meddle with it neither of which is my problem.
That may be true in general but if I were to receive a broken item and it was listed as working but no returns, I'd file a claim anyway. Sometimes I do pass these up too if the item is available from another seller.
