Both the IEEE and NIST surge guides say plug-in protectors are effective.

He is paid to promote plug-in protectors. He forgets to mention that responsible sources only recommend plug-in protectors when used in conjunction with what makes hundreds of thousands of joules irrelevant. If not protected by a 'whole house' protector, then plug-in protectors can and have even created house fires. Even with a UL Listing. Plug-in devices supplement what does effective protection: a proper earthing and a 'whole house' protector.

Spend $1 per protected appliance for 99.5% to 99.9% of the protection. Then enrich Bud by spending $20 or $85 per every appliance for an additional 0..2% protection.

He will post insults because he fears you might learn reality. He even lies about who he works for.

Integrity is provided by other manufacturers of responsible and effective protectors. These provide numbers for protection from direct lightning strikes (ie 50,000 amps). They need not post demeaning attacks to promote their product. Near zero protectors are promoted by one whose income is based in lies or by promoting half truths.

An informed homeowner starts by earthing a 'whole house' protector on a low impedance (ie less than 10 foot) connection. Then protection already inside every appliance should not be overwhelmed.
