Most people assume surges are bad and use surge protectors. However, undervolts/dips/brownouts are just as much if not more damaging and people unawares don't realize that a surge only protector does nothing for them. At my house, the dips are much much more frequent and is why I have a UPS for my TV and other entertainment gear.
true, surge protectors are actual snake oil. 99% of people get em thinking it will protect em from lightning strikes ...
It does though? At some distance the surge from lightning will be weak enought to let the surge protector save the computer?
