We bought a printer and it was having issues from the beginning. We thought at first it had to do with the WIFI, so we didn't say anything, but then more things were going wrong. I talked to the manufacturer, who said it needed to be replaced but we had to go through Asurion. Asurion "fixed" it and sent it back but we had our doubts. Sure enough, it was within the same month we were sending it in again. This time they just gave us an amazon gift card for the entire amount we had paid. Thankful for the warranty. They ultimately did the right thing, I just wish we could have gotten it done faster.

Asurion worked as intended.

After three years, my monitor failed. Asurion paid to send it to a repair center. I didn't save the box the monitor came in, and paid $23 to have it packaged up. They kept me informed of the various steps, such as en route, arrived, testing, and repair started. They discovered it could not economically be repaired and refunded my purchase price. The entire process from me telling them it was broken until the refund took 5 days. I am well satisfied with the service.
