Before Agreeing To This, Make Sure It Will FULLY Cover The Cost of Your Item!
I quickly agreed to this "protection" plan, only to later notice, it only covers up to $99.99 - not the $106.61 I've paid - for my new, soon-to-arrive, office chair! My chair cost $99.99, plus $6.62 in taxes. This Asurion "protection" plan costs $23.45, but only refunds $99.99, if there are headaches/problems with my new chair. So, I canceled my Asurion plan through Amazon, and will soon get my $23.45 refund!

Not worth purchasing.
Not worth purchasing. Nothing breaks until the insurance is expired.
