Honored the no lemon policy
3 attempts to repair my sons' Xbox. Took a lot of chats (a few strangely disconnected), a few calls and some pursuasion, but Asurion finally honored the terms of the agreement and refunded my purchase. You need to be aggressive with then though....

Asurion did what they said they would do. Couldn’t fix it so they replaced it.
My hubby cracked his 10 inch truck garmin by accident and assuring replaced it with no problems. They sent me an e-gift card and I purchased another one. I had to pay like $15 out of my pocket but it sure was better than 600. Awesome job Asurion and thank you for the no hassel.

No hassle protection!
Twice now I've had fish finders die on me prematurely. Both were covered by Asurion, and both times they quickly got me refunded so I could get new units and get back on the water!

Excellent Warranty Coverage – Fast, Fair, and Hassle-Free
I purchased the ASURION 3-Year Portable Electronic Accident Protection Plan ($500–$599.99) for an Android 13 8.8” touchscreen stereo installed in my BMW (CCC system). After about two years of normal use, the Android stereo stopped working completely. I filed a claim through Asurion’s website, and the process was straightforward. Initially, Asurion asked me to remove the unit and prepare it for return, advising that they would email me a prepaid shipping label. I de-installed the stereo from my car and packed it up as instructed. After two days passed without receiving the shipping label, I was about to follow up—when I received an email notifying me that Asurion had issued a full refund of $459.00. I did not have to ship the unit back. That level of service exceeded my expectations. The claim was handled quickly, communication was clear, and the resolution was fair and hassle-free. I purchase an Asurion protection plan with every high-dollar item I buy on Amazon. I’ve had to file a three claims over the years, and each time the experience has reinforced that this coverage is well worth the cost. When something fails outside the manufacturer’s warranty, it’s a relief knowing Asurion stands behind the product. Highly recommended for expensive electronics.

PROTECTION WITH ABSOLUTE EMPATHY & RESPECT
Had an issue with a product I purchased over a year ago along with an Asurion protection plan. Thank God I chose this extended plan. I was waiting for a return ticket you get it repaired and Asurion sent me a full refund. I am so grateful for Asurion and I encourage everyone to get these plans and get the added protection on products NOT made as they once were. We as buyers are terribly taken advantage of with the garbage sent to us that we pay very very high costs of. Asurion has NEVER failed me and the customer service reps are extraordinary and kind and very very respectful. Thank you to you all at Asurion, Johnny A. Cheers...
