Bud could have posted manufacturer specifications that claim
protection from each type of surge. But Bud is promoting protectors
that provide no such protection. So Bud does here what Bud does
everywhere - post insults.

Every responsible source says surge energy must be dissipated
someplace. Either inside the building or harmlessly in earth. Will
hundreds of thousands of joules be absorbed - made irrelevant - by a
tiny hundred joule protector? Of course not. Even protector
manufacturers that don't have an *always required earthing wire* will
not claim to provide that protection. Bud promotes ineffective
(unearthed) plug-in protectors. Instead of providing manufacturer
specs, Bud will always resort to mockery and insult. Sales are at
risk.

A protector is only as effective as its earth ground. Therefore
every facility that routinely suffers surges - and no damage - is very
careful about what provides that protection. Single point earth
ground. Where massive surge energy gets harmlessly dissipated.

No earth ground means no effective protection.
