Anybody know anything about this outfit and their claims?

About every nine months this sort of device comes around, repackaged but with the same extravagant promises.
It's pure, dishonest, BS.
These things do nothing a 30 cent capacitor can't do, and are completely useless in a residential setting. You just don't have enough motors starting up for them to matter. Because that's all they can do: correct the power factor of a cheap motor.
Open one up, and what do you find? A capacitor ... with, perhaps, some other things added on for marketing glitz ... an 'on' switch, an LED, etc.
Nor does it make one whit of difference where in the system this snake oil is applied ... at the panel, plugged into a receptacle, attached to the appliance. Save your money - and give these persistant high-pressure sales folks the deep six!

Residential kilowatt hour meters "ignore" power factor, and only record real power consumption. So a homeowner's electric bill will not be reduced by this device. It only makes sense to use at an industrial customer, where the power company does measure power factor along with real power consumption.
Oh, it might help if you connect a cap across a motor on a circuit (reducing reactive current) that is maxed out (breaker trips out after a while), but code may dictate better solutions to that sort of situation.
Some one should edit the link so that it doesn't come up in search engines and give them more free advertising.
Then again, if the top link comes up to their website, and every other link on the next 3 pages of search results are experts calling it BS, then maybe we should just leave it.
