Has anybody bought this "power saver" and tested it?
Logic is telling me, that it doesn't work.
"It uses a state of the art electrical technology to actively monitor and improve the power factor of electrical appliances ,suit for household or office. "
What do they mean with "improve"? Even if they change the power factor, wouldn't the active power drawn from the grid remain unchanged (with same load)?
