The EVS (Extreme Voltage Shutdown) feature of the device is far superior to available alternatives. Check out YouTube videos showing how these devices work. It's shocking what passes for "surge protection". EVS actually isolates equipment from the source of the surge. This is my third Furman and I will be back for more. My Furman PL rack unit has already saved me from overvoltage in a large apartment building. The thing is very cheap in comparison and has the same technology. It is not easy.
