Trustworthy
This protection plan is honest and true. I never purchase any electronics without it, not because I don't trust the product, but because anything can happen and ASURION has always come through when I needed them.

Prompt attention and quick refund
Awesome service. Purchased item at the end of 2023 and Asurion quickly, after return, refunded purchase price to my Amazon account. No hassle coverage. Have purchased Asurion on many purchases in the past and will in the future. Worth every penny. Saved a bunch in matters of money, quality, time and convenience.

Asurion does not honor their protection plans
Purchased a 3 year protection plan for my gaming monitor. The monitor broke after 2 years due to accidentally being dropped, which was covered under the plan. Asurion denied my claim saying they do not cover this issue. Thankfully Amazon customer service was able to help me return the monitor but this should have been handled through asurion not Amazon. If you buy a protection plan just know that asurion may not honor it if you need to use it. I have no confidence in asurion after my experience but am grateful for Amazon taking over the issue and fully resolving it for me.

Asurion stands behind their policy
I am very proud to know that Asurion stands behind their policy; if an item doesn't function, it should. The process was user-friendly and quick. Thank you, Asurion.
