Extended Warranty is worth it.
So glad I took out a three year warranty, my Shark Steam Mop stopped steaming.
Asurion refunded me with Amazon credit.
Thank you.

Ease of handling
Initially when I filed the claim online, I was erroneously informed to contact the manufacturer because I was still under their warranty. I learned that I was not. It’s for this reason they got 4 stars instead of 5.
I had to call and explain to Assurion. Once I did that they honored the extended warranty with no complications. I just had to return the defective device to them, they provided all prepaid UPS slip and I took it to UPS. They sent an Amazon gift card (via email) less than 48 hours after my UPS drop off. I enjoyed the ease of everything. Just make sure you call instead of handling the claim online. A person is always better.

Great protection plan service
My vacuum stopped holding a full charge after a little over a year, so I submitted a claim to Asurion. They immediately emailed me back with a gift card to cover the cost of replacing the vacuum. I was able to find an even more expensive vacuum that was on sale, so I'm very pleased with Asurion's protection plan.

Refunding/giftcards. Thank you
They were nice enough to replace my vacuum even though the battery was defective. They usually don't cover batteries. So it was a great. But they were nice enough to give me a gift card for the whole amount. Thanks
