The protection plan worked on my coffee pot. It was just over 14 months and started to leak. I first called amazon and they sent me a link to the protection plan. It was very easy to use. I received a Amazon gift card instead of a replacement. The price of the coffee pot had increased so you will receive the lower option. I did receive the total cost of the pot at the time I purchased it.

Great customer service.

I’m really happy with the appliance protection plan I got for my toaster. It was easy to set up, affordable, and gives me peace of mind. The customer service was also friendly and helpful. Definitely worth it!

I am satisfied because Asurion's response was quick, and they immediately refunded my money, so I can make the purchase again and protect it with Asurion again.

Fast and easy refund.

I purchased an air fryer and got a 3 year warranty on it from Asirion. The air fryer stopped working and I was expecting the warranty process to be complicated and didn’t have high hopes for getting a replacement. I was surprised though, not only was the website easy to navigate and user friendly, they responded immediately. I got a printable return postage receipt, dropped off the air fryer at a UPS store, and within a couple of days got a full refund in my Amazon account. Great fast service.
