Definitely Worth It
Quick and easy process. Coffee maker died and I had the insurance. Refunded and only ended up paying the price of insurance. Would do it again!

Claim was easy, speedy, and Amazon gift card was applied almost immediately.
I had to make a claim for a Ninja blender that was emitting an odor of burning or melting wires. I called a service representative thinking I might encounter a problem and was surprised. The agent was helpful and made the entire process so easy I applaud her! The Amazon gift card was posted to my account almost immediately after UPS picked the product up. I have decided that for products with a large number of parts and electronics that can fail I will purchase Asurion protection.

Asurion "Assures" nothing!
Asurion has terrible Customer Support. All machine based. They give you no phone # for human interaction. Their online Support process is very close-ended. It is a checklist designed to frustrate purchasers whose issue lies outside only the very issue.
My issue: I bought "Cuisinart TOB-40FR Custom Classic Toaster Oven Broiler, Silver (Renewed)" on May 26, 2024. It stated it had a 90 day warranty. So I bought an Asurion Protection Plan also to cover it for 3 years. The toaster started flaking off metal finish inside the oven over the cooking area. I tried to file a claim with Asurion and they told me the Manufacturers warranty was still in effect and I should contact Cuisinart. This despite the oven was sold with a Amazon Renewed verbiage stating a 90 day warranty.
And they have nothing on their "Machine Checklist" to cover this eventuality. And I would assume I am not the only one who takes the "Renewed" route and backs it up with a "Protection Plan".
They will frustrate you no end. I suspect, like many insurances, they seek to deny, deny, deny, in hopes the purchaser will give up.

GIFT CARD AS REPLACEMENT, NO CHOICE OF CHECK OR REPLACEMENT. GOOD COMPANY
PROS:
* A decent company, responsive and fair.
* Allows you to buy items from anywhere you want, and buy the warranty at Amazon.
* Provides better coverage than other warranties, and covers more, including breakage!
CON:
They don't send you a check in order to buy wherever you want, send a replacement, or give you a choice. Instead, they send you an Amazon Gift Card. That's OK if you're a big Amazon shopper, but sometimes, you can get a better price elsewhere.
