Received giftcard money to replace my plan-protected malfunctioning motherboard
I've been subscribing to the Asurion protection plan for a while. Recently, an Asus Prime PC motherboard I had bought a few months ago on Amazon stopped working well. I ended up considering filing a claim with Asurion to see if they would either fix/replace it or issue the purchase price money, so I could buy the failed electronics replacement component again for my custom-built PC. I went to the protection plan's website and started the claim filing process but couldn't find the category my failed component would be under in order to select it from the drop-down list. I ended up messaging the live customer service. The chat messaging was somewhat slow, the agent told me they were experiencing some communication delays throughout their systems. Ultimately, the agent was very kind and understanding, and completed the claim filing process for me on her side by asking me to provide the necessary info such as the item's product name, date of purchase, price before taxes, etc. I received a printable UPS shipping label in the email, printed it, and returned the item in the mail. Approximately 2 days later, I received an Amazon giftcard code in the email with the dollar amount equal to the item's price before the sales tax. Then I redeemed the giftcard code on the Amazon page and proceeded to apply the giftcard money to my next purchase of a replacement Asus prime motherboard, and it all worked out successfully. Therefore, I had no issues with the protection plan service and recommend it to others.

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.

Easy Claims Process
It is not a long complicated process to file and resolve a claim. Be warned--sometimes they will want you to send back the defective or damaged product, even if it's not worth the shipping ---they pay. Overall worth the investment though.
