Quick response
Almost as soon as I described my problem with the screen I purchased, I was approved for a refund in the defective product.
Excellent customer service. I have used Asurion many times but this was my first claim. Keep up the good customer service.

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!
