Surprisingly great service!
Surprisingly great service. I just didn’t expect my claim to be handled so efficiently. Replaced the purchase price of my printer that was 3 years into a 4 year protection plan.

Works, but reimbursement for damaged items come via Amazon Gift Card, not Cash
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

Don't trust asurion
I first contacted Amazon for this product when I didn't receive this. I bought this back in October 22nd or 23rd with my Lenovo chromebook idea pad flex which it's now December 16th on a Friday night I have yet to receive it. I first contacted Amazon about it November 3rd they said to give asurion a week to back it up for the email delivery. Waited a couple weeks ans nothing happened, contacted Amazon and they put me on with asurion which I then revived a text through tech support saying I'll receive it soon, give them 24 hours to respond with it. Going through 2 links and 2 sites, an email verification a phone number verification and an Amazon sign in "Sorry, we are unable to find your plan." Was the response I was given after all of that. It then put me through the sign-ins again, at the very start of the last 45 minutes hence why I'm writing this. Not to mention the last month I've been trying to contact them for email delivery of my protection plan. I spent $108+ tax on the 4 year protection plan on the upgraded version of my chromebook IdeaPad, which was a gift to someome special to me. Now if It shuts down tomorrow it's not going to get the honored 4 year protection plan, warranty. The device was expensive and asurion can't even honor their own protection plans.
