This is one of the best warranty companies out there.
I have had my warranties with Asurion for years, and they are one of the best warranty companies out there. When filing a claim, the process is very easy. I finished the entire process in less than 5 minutes. The service was amazing and the lay-out and appearance of the website was simple to use. The protection plan cost was reasonable.

Quick and easy
My water kettle just stopped working after a year. Once I boxed up and returned the kettle, Asurion refunded my account.
