Environmental Potentials whole house surge protection, can I get your opinions?


I'd like to protect my whole house from surges rather than use individual units around the house.
The power on the NE is pretty good, but I know all it takes one bad zap. Have any of you installed this unit and do you think it works?

I have a  Power surge protector on my meter to my house the electric company put it on there for me it cost five dollars a month .

Sorry, I was away for a while and missed the fireworks.
In any case, my electric was gone over in 2000, the grounding, which was never tested, looks like a submerged rod just outside the house with a clamp holding a thick wire (copper?). 
Any ideas finding someone on Long Island to do this testing?
