It is worth purchasing a Protection Plan on an unfamiliar item
Bought a 3-year protection plan for a nut milk maker machine for $5.99. It was a fairly new kitchen item in our household and we were not familiar with the brand. So, I bought the plan for a piece (peace) of mind. The machine worked nicely for about 18-20 months with daily use until it tripped the circuit outlet. My initial chat with Asurion did not go as I expected due to discrepancy on their end as they see a protection plan for the nut milk maker as a sporting goods valued between $100-$199, not as a kitchen item valued between $30-$39.99. ( I had bought 3 different protection plan on th same day for multiple items purchased on Prime Days). They were looking at a different plan and I was unable to get them to "scroll over" to the appropriate protection plan. I tried again on a different day during the first hour of their contact hours and had a cheerful Asurion agent who was able to find the appropriate kitchen item protection plan. It was a simple and thorough conversation and transaction. I was refunded within hours after I packed up and dropped off the damaged item out to UPS. Moral of the story: Asurion Protection Plan is worth it and contact them at the start of their first day shift, not at the end of their evening shift.

No hassle refund
So glad I bought the plan. After 2.5 years of everyday use of my toaster, it quit working. Contacted Asurion, they emailed a shipping label. A few hours after I dropped the package off at UPS, I had the refund in my Amazon account. Very easy, no hassles.

Very bad
This guys are just an eye wash, they do not cover anything but will charge you. I bought Hand Blender and it broke in couple of months and I took 3 year protection from Asurion. When I contacted them about the issue, they said it is not started, go to manufacturer. I reached out to Amazon and they replaced it for me. Now again it broke. I reached out to asurion again. Now they say it is not contract. what is the point of having protection. Waste of time and money. I will not recommend this to anyone. This is a fraud protection.
