Most times when you get a surge in voltage you don't even know it, so what's the problem? Each time that happens your equipment suffers slight damage and it shortens its life. Ok, got that… but don't surge protectors solve that problem? Not really, because most surge protectors on the market are clamp-and-divert devices, making them a tad slow and unreliable. Even worse, when they finally act, they bring the power below the safe zone line which in itself is a kind of surge that also dings your equipment.

ZeroSurge's WVR-TSC technology solves that problem by first filtering off the surge and then cancels the remaining surge frequencies, much like noise cancellation. ZeroSurge claims it's 100% effective even against lightning strikes and supplies the military with this technology. Total surge protection can be yours today for $200 to $580, depending on the model you want. — Ken Sander
