Quick and Fantastic Service!
I include the additional protection for all of my high dollar purchases. This was the first time I have ever had to use it. I had an extension to provide additional screens to my laptop. Unfortunately, it developed an issue. Submitting a claim was easy and straightforward. UPS came the next day to pick it up and I was notified in just a couple of days that it was received. Only a couple of days after that, I received an email stating that my laptop screens were not repairable and I was given an Amazon card for the entire purchase price. I could not have been more pleased, as the purchase price was $599 and was a huge splurge for me in the first place. I was able to quickly replace the screens and back in business in no time. I would recommend this protection plan for any high dollar purchase.

They paid on the policy
I bought a four year replacement policy on my modem and two years into its lifespan it stopped working. I trouble shot with the company but we eventually determined it was dead. I contacted Asurion, they sent me a pre-paid address label, I mailed the defective modem, they found that it was dead and deposited a credit in the amount of the original purchase in my Amazon account, all within a few days. I am quite happy with the service. Just so you know, the reimbursement is through a gift card at Amazon which you can draw down against your purchases; it is not CASH.

Nearly 3 years later, Asurion had my back :)
In Nov of 2017 I bought a $900 35" Ultra wide PC monitor for Gaming and Work. It was made by a company called AOC/Envision and I bought it through amazon. The monitor had a 3 year warranty that I was still within but they said no to a defect that they said was only covered for 1 year, even though it wasn't the type of defect that was only covered for 1 year. LUCKILY, back in 2017 I had purchased an Asurion insurance policy with this monitor. I told an Asurion agent in a instant messaging chat window on the Asurion website my problem and she sent me postage in an email. I shipped my product and in 5 days from shipping it I received a text telling me that it was beyond repair and I would be getting a FULL REFUND! Not 2hr later, in an email, there it was, an amazon gift card code for $900 I will not be making any big purchases without an Asurion plan going forward. Happy customer Don't buy anything AOC

Received a refund
I purchased the 4-year protection plan offered at the time I purchased a refurbished printer. Seven months later the printer failed, so I went searching through my Amazon orders for my protection plan and located it. Once I created an account on Asurion's website it showed the the plan but it was not attached to a specific purchase, so I had to locate and upload the invoice for my printer. Once that was done, the policy still wasn't linked for some unknown reason. I proceeded to start the claim anyway stating that my printer had failed and I received an immediate reply stating that a box would be shipped to me for me to return the printer for inspection/repair. After a week I hadn't seen any additional info so I called their support phone #. The service was very good and they had to create a new case to replace the one I started online, and they assured me that a shipping box would be sent. About a week later I did receive the box with a prepaid shipping label to return the item by UPS. I packaged the printer up and sent it off. I received updates stating that they received it, were looking at it and attempting repairs. Everything appeared to be going along well, then out of the blue they sent me a notification of a full refund in the form of an Amazon gift card. Overall I'm satisfied and I'm glad I purchased the coverage.
