The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.

Got full credit back. Great service

Sent us Amazon credit for the full amount after our lounge chairs fell apart in less than a year. Great service!

Don't waste your time. They'll just deny claim

Not a very reliable form of insurance. I had to file a claim on a 2 month old bedframe and they gave me the run around until I contacted Amazon.

No hassle to file and get a claim resolved.

I have to say, I expected a lot of hoops to jump through. Companies are all very eager to take your money, but when it comes time to pay out, in this case (Product Insurance) quite often it is a different story. But to my surprise that is not the case with Asurion. I submited my claim, and a few days latter I received my check. At 77 and retired from the computer field i have seen alot of things with companies that do not care about customer service and satisfaction. But when you make a purchase from Amazon with their 30 day return policy and Asurion insurance. You can't beat it.
