When you buy an extended warranty, you are betting that you just bought the worst piece of crap in the world. Most crap will out last the extended warranty. We bought a GE washer; because, the add said that it was quiet. After about a month it started sounding like a jet taking off, they tried to repair it twice, them they replaced it with a new one. 5 years later when it died we were happy to buy a new one, no way were we going to keep that F14 in our laundry room. We bought a Dryer 3 years 2 months the motor died. The extended warranty they offered was for 3 years, I am glad I didn't buy that one.
I have bought two extended warranties, one was on a refurbished digital camera, refurbished electronics generally have a 30 day warranty and are not always returned to original factory specifications, as they say. I bought a refurbished name brand DVD recorder, after one week the cooling fan started making noise, refurbished in this case was probably spraying WD40 on the fan, took it back and bought a the cheapo no name brand that is still working today. The other was the Toyota Prius, I figure that with all the high tech electronics one failure could easily cost more than the warranty, $1100 for 7 years 75000 miles.
If the extended warranty is more than 1% of the original price per year it is a rip-off and if they are only offering 1 or 2 years that is not enough, for most things you need 5 to 7 years to get to the normal failure zone.
All bets are off for the future, from what I hear, there are problems with the lead-free solder in electronics, we shall see in 2-3 years, I hope it is not as bad a the Y2K fiasco. I was on call for Y2K, what a joke.
