Just remember when you buy any warranty or insurance you're dealing with an entity who business interest is to take your money and provide no services. They have a deep understanding of the product and know which issues most commonly come up that cost them money. They write exclusions for it in the contract in ways that are difficult for you to discover. They'll have a claims dept whose job it is to convince you that you don't have a valid claim, or deny it. They'll make you jump through hoops if you have a valid claim hoping you'll give up.
Not every company does all these things, but they wouldn't sell you the policy/warranty if the price you pay wasn't far more than what they expect to pay out to the average customer in claims after taking into account all their expenses (staff, office space, taxes etc.) and expected profit margin.
