For real science read the IEEE and NIST guides. Both say plug-in
suppressors are effective.

Both Bud citations show what a plug-in protector can do. Since it
has no earthing and is too close to appliances, the plug-in protector
earthed that surge 8000 volts destructively through an adjacent TV -
Page 42 Figure 8.

The NIST is even blunter about Bud's protectors that don't have
earthing:
A very important point to keep in mind is that your
surge protector will work by diverting the surges to
ground. The best surge protection in the world can
be useless if grounding is not done properly.

Why did the plug-in protectors divert a surge 8000 volts
destructively through the TV? NIST also explains what Bud's other
citation shows on Page 42 Figure 8.

And again, Bud posts insults while never providing the only relevant
fact. Protectors promoted by Bud do not even claim to provide that
protection. Why does the professional sales promoter not provide
numeric specifications for products he recommends? Again - no plug-in
protector will even claim to provide that protection. Bud must post
insults incessantly so that you will forget what he cannot post. A
spec that claims protection.
