First off the warranty only covers defects in materials in workmanship, defects that are not going to appear until after the regular warranty expires, so you have to qualify the repair or replacement on the product. You are more likely to have your car written off in an accident, which you have different insurance for. The gamble the carrier is taking is very small on the defect warranty extension, unless the product you purchased was a complete lemon and you can bet the warranty you purchased won't cover that, it's not anti-lemon insurance.
This is the way I have to look at it, It's buying extra insurance. I'm old, if I bought extra insurance for everything I owned up to now, the amount would be staggering and depressing. All of the extended warranties would have expired by now, I'm still using an iPhone 5S and it survived great without an extended warranty. Even my life insurance company sent me most of my money back, I am no longer under warranty. I'm not buying extra life insurance now :/ somebody else can deal with that.
Can't argue that insurance is not a bad thing but it has been my observation that it is expensive piece of mind and you can never have enough. Go out and buy something nice and now you need to pay more insurance? Might better put that money into lottery tickets and take real good care of your stuff.
