Aren't these similar to some device they used to market on TV that you could plug your 120V window A/C or refrigerator into and save money??? I can't find a link to that specific one, but I found a couple doozies
I've yet to have anyone approach me about hooking one of these up...
Is the Power-Save 1200™ easy to (install)
We recommend installation by an electrician. The unit comes with complete installation instructions. It installs in about 20-30 minutes
$300!!!
