I have to say, I expected a lot of hoops to jump through. Companies are all very eager to take your money, but when it comes time to pay out, in this case (Product Insurance) quite often it is a different story. But to my surprise that is not the case with Asurion. I submited my claim, and a few days latter I received my check. At 77 and retired from the computer field i have seen alot of things with companies that do not care about customer service and satisfaction. But when you make a purchase from Amazon with their 30 day return policy and Asurion insurance. You can't beat it.

Amazing customer support

I think all customer service should be like this. My footstool was ripping and I told them and they sent me a check. No questions asked and it came like within a week. I love them.
