ASURION EXTENDED WARRANTIES
I was skeptical that my ASURION warranty would be honored since it was not an easy process to submit claim and required following up several times. Not as easy as buying it initially for a product on check out at amazon. Once the burdensome process was completed on my end, It was easy load the gift card issued for the warranty to my Amazon account. I would definitely look at warranty policies closer though before purchasing one. Good luck if you decide to purchase extended warranty.

Waste of Money and Time
It’s useless buying this protection plan. They will not help you with your issue. They will refer you back to the seller. What’s the point of buying a protection plan when they refuse to help? I DO NOT recommend purchasing this plan. Total waste of money and time.
