I own this product but DOE guidance is for this product to be the last line of defense. Many folks think that a surge supressor will stop electronics from being fried due to a nearby lightning strike or a direct lightning strike...um 3km of atmosphere did not protect against a lightning strike and you think that few milimiters of diodes will?! NO!

What protects against those strikes is house ground....that's why it's imperative to employ a whole house surge suppressor that connects to your breakout box...at best it's a straight copper wire less than 6" that goes to the surge suppressor from the breakout box......why?! Well we are humans are lazy, but it's our nature since nature is lazy...i.e...electricity seeks the least resistance/shortest path to ground....if you provide a that exit via whole house surge suppressor then all the energy will be shunted to the ground without touching your electronics.

The in house surge suppressors like this one are good for remnant EMP created by the strike or any internal household surges i.e.: AC turns on, Washer turns on, heater turns on etc. They are not meant to absorb high energy spikes they are meant to provide protection against small transients.

SO my advice to you all is as follows:

1) MAKE CERTAIN YOU HAVE A GOOD SOLID GROUND
2) Get Whole house surge protector (they are as low as $30 D-square makes great ones).
3) Use Tier 3 surge suppressors like these on all electronics
4) For sensitive electronics get an in-line UPS (always on UPS).
5) Surge protect your COAX and Phone Lines...the COAX get a dedicated COAX suppressor and connect it to the ground...make certain there is at least 20 feet of coax between the suppressor and the sensitive equipment. I would just connect it right at the point the coax enters my house.
