ASURION was fantastic as always. Purchased a Nespresso machine for my DIL which she absolutely loved and two months before warranty expired it started leaking which broke her heart. ASURION stood behind their warranty and refunded purchase price which I transferred to my DIL so she could purchase another machine. That’s why I never hesitate to buy their warranty’s and why I love shopping Amazon! Both companies represent their clients well. Thanks to both!

Quick,immediate action

Very quick refund. I reported the issue, same day reply with instructions on how to return, free postage and as soon as Asurion was notified id dropped off at UPS, within the hour my refund was in my account. A pleasant experience as no waiting period, nothing. I’m able to replace product almost immediately. Thank you, I’ll be covering all my expensive items with this company. Five stars all around.

Great plan, easy refund process

Asurion refunded the cost of my tv when the screen started to fail. Highly recommend buying the protection plan as Asurion makes the refund process easy!
