Query: Greate Product saved my pc, lamp, and two external hardrives

Someone in my dorm caused a surge. All the lights dimmed and my panamax sacrificed itself. Although I lost it all of my electronics are safe. I called the company and im sending in $10 and getting a new one. Also I am upgrading for 50% off to the M8-EX! Can't wait! Awesome Product, highly recommend.
