Most of the things I buy are quite simple and far from "high-end"
I do lots of research before buying, read reviews, etc. to try to find products with a record of minimal problems.
In spite of that, we do run into serious problems with some stuff. 
The fridge I bought last August, a "Whirlpool", draws numerous excellent reviews.
I bought it on sale — 10% off regular price, with a "free" icemaker promotion — packaged separately — which I sold for $65.00
There is a very minor cosmetic issue for which they refunded ~$50
I bought a 5-year extended warranty for ~$100
Hopefully, it'll serve us well without serious issues!
