I bought one for my wife's laptop. 18 months after we bought it my 12 year old dropped it and it stopped running. Sent it to the authorized repair place and they fixed it for the shipping charge. Saved me about 4 times the cost of the warranty.
Bought the way overpriced "road hazard" warranty on a new set of Michelins a couple of months ago on a hunch. Got a screw in the sidewall. Got a new tire with no hassle. Saved 1.5 x's the cost of the road hazard warranty.
Once bought a 100 disc CD player that broke not long after the regular warranty ran out. Sold it at a garage sale for $5. Two days later got a reminder in the mail that the extended warranty on the CD player was about to run out. Had forgotten all about it.
When you have been a life long Cardinal football fan you buy all the warranties you can afford.
