    protection plan is easy.
    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.

    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.
