Just confirming that this protection plan actually works. Asurion first told me that they'd try and repair my item. Likely, they couldn't find someone to repair the type of item I bought (KVM), so they offered payment (original cost of the item) via Amazon Gift Card. Giving 4 out of 5 stars -> 4 instead of 5 because Amazon Gift Card isn't Cash. Cash is always better.

When Acer's Warranty Policy left my high and dry, Asurion Protection came to the rescue

My Acer Monitor was damaged during a brownout due to a lightning strike close to my house; Acer Customer Support told me that their warranty did not cover this sort of damage but luckily for me, Asurion Protection did. I simply mailed them the item for repairs with their shipping label, and once they realized that the item was damaged beyond repair, they emailed me an Amazon Gift Card Code with the amount spent on the monitor; I'm extremely happy that I bought their protection because without it, I would have had to pay the price of a new monitor to get my PC Setup back into commission. Many Thanks, Asurion Protection
