Amazing, effortless, easy!
Excellent experience! I made a claim and they immediately issued an Amazon gift card for reimbursement. Entire process from start to finish was probably 2 minutes or less. Amazing, effortless, easy! Will purchase again for any other items that qualify.

ASURION 4-Year Housewares Plan - An Excellent ROI
The ASURION 4 Year housewares protection plan was definitely one of the best investments that I've made to date. I had a large, 12,000 BTU portable air conditioner that stopped working properly in its third year of use--one year after the manufacturer's warranty had expired--essentially leaving me with a glorified hot air fan. I proceeded to file a claim on my ASURION 4 Year housewares protection plan. The process could not have been easier and did not require much documentation since the plan was already linked to my prior purchase of the AC off Amazon. I received an Amazon gift card within minutes of filing the claim, thereby definitively demonstrating ASURION's broad coverage scope, reliability, and overall value. As such, I used part of the gift card to purchase another four-year plan on a replacement AC unit that's now sitting in my office. Hopefully, I will not need to use it, but it's good to know that I have coverage if needed.

Asurion coverage was worth every penny!
Bought a window AC in 2020 and was offered Asurion coverage at checkout. Paid $39 for the 4 year plan and never expceted it would be worth the money paid. Honestly, never expected to even use it. That said...the AC failed about 2 years later so I made a claim online. The claim went in but required a call to an Asurion rep (very nice guy on the phone). He asked a few questions then told me the claim was approved. Total time to for the entire process was about 15 mins. I had the choice of having it repaired or a refund check. I asked for the refund. An emailed pre-paid UPS label was recieved a few minites later and the guy said they'd mail me a check when the UPS package was received, so I dropped it off at UPS. Three weeks later I had a check in my hand for $399 (the excact cost I paid for the AC unit 2 years before minus taxes paid). Really easy process and quick time to receive the check. The only thing to note is that if you make a purchase like that (large electronic or home appliance)...keep that box and packaging. Luckily I had it all and just popped it back into the box for shipment. Not sure how I would have dealt with that if I hadn't saved the box. Thank you Asurion, for delivering on your promise of quick and easy extended warranty payment. I'll defintely purchase the plan again with my replacement AC!
