I’m a Never. I haven’t bought hardly anything in the way of hardware - I’m in an apartment that came with its kitchen appliances installed. My car has a warranty, but I bought it from a dealer and didn’t fill out a card. My computer was built by my brother and didn’t come with a card.
My projector, dvd player, and so on may have come with cards, but I haven’t bothered. In my experience when something like that dies it’s usually been long enough that it’s time to buy a new one. It ain’t like warranties cover the bulbs, after all.
