Meanwhile, informed consumers learn from engineers who have been doing this stuff for decades. View manufacturer specs for that $100 protector or the Furman devices selling for more. Their specs are similar to the $4.99 protector.

Take a $3 power strip. Add some ten cent protector parts. It sells for $7 in the grocery store. Or $150 from Monster Cable.

Monster has a long history of identifying scams. Then selling equivalent products for even higher prices. Did you know speaker wire has polarity? Monster even sold speaker wire marked for the speaker and amp ends. Claimed that sound was perverted if that wire was reversed. And then sold that $7 speaker wire for $70.

Monster is simply doing same with surge protectors. A responsible poster who listed those manufacturers also listed manufacturer spec numbers that claim that protection. No specs provided for one simple reason. Those manufacturers do not claim protection from typically destructive surges.

Informed homeowners install the superior protection that costs about $1 per protected appliance. Based in science well proven even 100 years ago. A solution used everywhere that damage cannot happen. And makes even direct lightning strikes irrelevant. Also obvious once one selects a protector using engineering concepts. Which means spec numbers. And which means ignoring recommendation that do not also provide the reasons why - and spec numbers.

How does that magic box rated at hundreds of joules absorb surges that are hundred of thousands of joules? Damning numbers.
