Be careful purchasing this.
We bought this for an ice-cream maker - they never sent the initial startup you bought this email. So I had to fight with them that yeah we bought it. Then they classified it as an ice-maker - important for pictures later . Then we had bought the machine and insurance partially with gift cards not a big deal, right? - well, the machine cost $300ish but showed on the receipt total as $180ish - guess which amount they wanted to pay out for? Then they wanted pictures showing serial number and such on the machine. I sent them pictures of each side clearly showing no stickers. Take more pictures of the front and top because what you took wasn't good - MAYBE because you thought it was an ice-maker... Take a picture showing what doesn't work - it will spin and move, but the compressor broke so it won't get cold - NOT GETTING COLD is something I can't show... it was fun being told to take a video showing it not getting cold only to tell them yeah no I am not wasting my time doing that. There was a lot of repetitive stuff but they did eventually pay out the correct amount. Would I buy it again? Yes. Is it as easy as they make it out to be? No. Did I WANT to give this review? No, because I didn't want to leave a negative review. I am a very charming, nice, and personable guy that didn't want to be mean. Keep pestering me enough about leave a review about how great we are and you will get the review you probably did not want.

You can trust ASURION warranties!
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.
