More expensive solution is that Belkin protector. Serious and significant protection is routine with one 'whole house' protector and a $10 ground rod. To make their protection a little better, high reliability facilities spend massively on extensive grounding. Because that earth ground determines protection.

Costs approach zero if protection is installed when footing are poured.

For homes, one 'whole house' protector costs about $1 per protected appliance. How much per appliance for that Belkin with its mythical warranty? That Belkin has all but no earthing. It does not even claim protection in its numeric specs. Its warranty is so full of exemptions as to not be honored.

How to identify least effective protector? One characteristic: it has a big buck warranty. We all learn this from free markets. Since GM has a clearly superior warranty, then GM products are superior to Honda? Nonsense. Because GM's hyped warranty is so much better, then we can predict from free market history that GM products are the least reliable.

Why do high reliability facilities use 'whole house' protectors? Because that solution is effective. And may cost tens or 100 times less money per protected appliance.

More expensive and least reliable solutions are plug-in protectors such as that Belkin that does not even claim to provide effective protection in manufacturer's numeric specs. Listed in the previous post is a less expensive and clearly superior solution. The only solution implemented in facilities that must never suffer damage.
