You know electricity and this is complete bull-—right? Thanks
I worked Summers as an electrician's helper (better than being a plumber's helper), and this product is silly. It's shameful that people push this kind of sham on the public.
If someone wants a surge or spike protector, that's great, and they will help reduce damaging spikes to sensitive electrical equipment like computers, but you can buy surge protectors for $20 ~ $30 for a good one.
There are energy saving surge protectors designed to turn off a related electronic components when the main component is turned off; for example, powering off a DVD player, amp, etc, when a TV is turned off in a home theater setup. Of course you can also just buy a simple $10 power strip and flip the power switch manually to achieve the same result.
