not all surges are from lightning i once had a wind storm which was blowing a tree into hydro wires and caused surges
Those other 'surges' are electrically equivalent to lightning. Other surges are created by falling wires, rodents (also called squirrels), stray cars, and linemen errors. Surges from those faults also are not averted by adjacent (plug-in) protectors. Lightning is simply a typical example.
Only reason for surge protection is from surges that typically do damage - ie lightning and those other sources. Adjacent protectors must somehow and magically block or absorb those transients. Specification numbers make it obvious it does not happen.
Effective protectors from all type of surges (including lightning) are effective, must not fail due to any of those surges (including lightning), and typically costs tens or 100 times less money per protected appliance.
Again, protection is always about where hundreds of thousands of joules dissipate. Even the protector must not fail; must remain functional even after multiple direct lightning strikes. This superior solution (what is found in facilities that cannot have damage) is readily available from other manufacturers known for their integrity.
Real men earth one 'whole house' protector.
