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.
