I had a steam mop that did a great job cleaning my floor and Lazy Boy. After 2 years of using it the mop didn’t work anymore. I remember I bought this protection. I was shocked how easy and fast the claim was paid. I was able to buy a new mop and get another 3 year warranty. I would definitely recommend this for household appliances.

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.
