I read everything I could find on the Internet about the product; though there wasn't much info to find, the products claims seemed plausible. So I ordered 3 (was a greater discount). Waited about 5-6 weeks. Then a package arrived that looked like it had had a rough journey when the packaging and product wrap practically fell apart. At least the product appeared intact. Instructions ... err ..."Plug it in and Save" - okay! ... err waiting ... still waiting ... getting quite dusty ... but ... nope! ... nothing. Not even a penny saved ... though I suspect it has in fact consumed some electricity? But almost 12 months later still NOT gotten the 2 missing products. Neither have I received responses to any of my attempts to get answers to my issues; such as: missing items and how many decades before I see savings? User's recommendation: Product claims as hollow as the inside of the product. THIS IS A SCAM. Buy at your PERIL!.
