Cover yourself!
My HP printer just stopped printing. Spent over 4 1/2 with HP Support doing all kinds of technical experiments with even the most complex Factory Restarts, this printer kept saying everything was working but it wouldn't print. HP finally declared it a hardware defective; told I needed a new printer and to recycle this one (less than 1 1/2 years old - don't make like they used to!). Called Asurion, who immediately processed a claim and arranged for a pickup of the defective printer since I can't drive. Fast quality service worth every penny if you're buying any kind of devices in today's world.

Asurion is a great protection plan.
Asurion is a great product. I purchased a 3-piece cordless phones in 2022 and added the Asurion protection. Just recently the phones went out. I contacted Asurion and within 2 hours I had a gift card deposited in my Amazon account. I purchased new phones with the gift card and of course added the Asurion protection. I highly recommend Asurion protection plan.

Glad we got it! And will most definitely buy it for our future products!
Great experience! We always bought Asurion Protection on a lot of our electronics to be on the cautious side. We recently had one of those electronics give out on its 3rd year, and we luckily had purchased the Asurion Protection Plan. The claims process was easy, took less than 5 minutes. I packaged the electronic the following day and dropped it off with the shipping label they gave me. I received a full refund of my product within hours of having the returned item dropped off. I am glad we bought Asurion Protection for our other electronics, and will continue to buy it for our future products (not just electronics). Very pleased with how fast and reliable they were, and enjoying the comfort of knowing our products are protected.

Protection Paid Off...Super Quick
The protection plan was easy to obtain and even easier to submit a claim. It came in very handy, especially with a device that you know is important but are uncertain if it will endure "the test of time." Knowing I had the Asurion plan to begin with made me more confident to purchase the device. When the claim needed to be filed it was a breeze and the process from start to reimbursement was super quick. Was happy to get the full paid price back and used it to buy a replacement right away. It's a no-brainer, get it with any electronics...peace of mind so worth it!
