Hassle free experience!
Very impressed by how easy it was to file a claim online. I was expecting a hassle or a run around to make it more work than necessary, to discourage claims, but nope, super simple! I initially thought I would get a replacement product, but instead, they sent an Amazon e-gift card, which was even better, since the price of the product went up from when I originally bought it. With the gift card, I was able to replace it with a cheaper item. Definitely worth the low cost insurance!

Protection contract
Great company I’ve had them before and have been fortunate than I never have to use them, but I enjoy the protection.

Great support and warranty
The leaf blower has not been so great and then a failure. The warranty and support from Asurion was fantastic. Glad I made the purchase.
