Relief and Security!
I have Asurion on a few of my things at my home. I have never had to use it so far. I at least know it’s there if I need to.

great for certain items
i am an infrequent buyer of the assurion warranties but do use them for stuff i think might be something i'd claim on like the very low priced inflatable paddleboard i got. i can't imagine the thig lasting 2 years but the warranty makes that a no brainer. i have only once in my history had to make a claim and it was an easy process where they just automatically refunded the price of the item
