Dishonest Company
Purchased a Halowview BT7 RV Backup Camera along with the Haloview BTC 129 RV Side Cameras for a little over $550 in September of 2022. Due to a couple of poor reviews on this manufacturer I opted to purchase the 3-year $500-$599 extended warranty for both items at checkout. One of the side cameras went out and when I contacted Asurion they advised me that it was not covered under the warranty that I purchased. They said they will only cover one item at a time on an Amazon order and I was only covered for the $339.57 Backup camera on the order. I tried to point out that I would not purchase a warranty for $500-$599 on something valued at only $339.57. Asurion tried to blame it on Amazon and advised that their terms clearly state they only cover one item per invoice and that I had no warranty on the second item. When questioned about how a consumer is supposed to know this information, they advised that I should have read all their terms on their website. They refused to repair or replace the defective item even after confirming that the policy value was for $500-$599. Total waste of money!

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.
