The protection plan was easy to obtain and even easier to submit a claim. It came in very handy, especially with a device that you know is important but are uncertain if it will endure "the test of time." Knowing I had the Asurion plan to begin with made me more confident to purchase the device. When the claim needed to be filed it was a breeze and the process from start to reimbursement was super quick. Was happy to get the full paid price back and used it to buy a replacement right away. It's a no-brainer, get it with any electronics...peace of mind so worth it!

Refunded my purchase price

I purchased the "TESmart" 2 computer KVM Switch. I always get the added warranty these day for electronics and I am glad I did. It has now been 3 years and the unit has stopped working correctly. It would switch between computers but the mouse and keyboard stopped working for one of the computers. I'm not sure exactly which component stopped working because the keyboard and mouse worked fine for the other computer. I did plugged the mouse and keyboard directly to the computer in question and they worked fine. I believe the "push threw" stopped for my W11 computer, meanwhile, the W7 computer keeps trucking on. I say all that to say this, it's worth paying a few dollars more to get that little bit of extra security on the electronics these days. Unfortunately the prices have gone up on the KVM switches, at least the ones worth buying so I am in search of a new one now. ASURION was easy to work with. It wasn't that much of a hassle. The slight glitch I experienced was their automatic system didn't register my claim correctly. Only mistake I made was making the claim over a weekend. I would say if you make a claim do it during the normal business hours. I was able to chat with an agent during working hours and they were able to remedy the issue quickly. I did have to ship the KVM switch and its components to Asurion but they paid for shipping and once I was able to package and ship the unit back, Asurion refunded my purchase price completely with an Amazon Gift Card. So, all in all, it's all good!
