Fast and easy but I dont trust the process to be fully automated.
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.

My great experience with Asurion
Very easy to use, no hassle, everything was done quickly online (5 minutes or so), and the reimbursement check was received promptly. Exactly as advertised. Make sure you keep your Asurion info in a folder that you can easily find in a couple of years. I guess it matters on what you are protecting, but for me and my gaming chair, this was so worth it, worth it, worth it!

ASURION REFUND
I couldn’t be more pleased with ASURION. I had a 3 year furniture protection plan, when I emailed them with my problem they did not hesitate. I got a response from them quickly. It is well worth the money to get a Protection Plan. I received a check from ASURION for the price I had paid.

A must have
I thought this was going to be a waste of money but I couldn't have been more wrong. I purchased this for a piece of furniture and after about two and a half years the piece started falling apart. So again I thought I was wasting my time but I called them up and the person that answered the phone was the kindest and the most understanding person. I proceeded to tell her why I was calling and of the issues I was having and within just a couple minutes and just a couple more questions I had an Amazon gift card for the amount of the full purchase price, I received a full refund. And this was after two and a half years. The bottom line is you can not go wrong with the Asurion 3 year Protection Plan. A MUST HAVE!!!
