I use the bill payer so I have an average monthly bill that is adjusted for usage every 6 months. I pulled up my account and my usage/bill has gone down on average $60 a month after installation of the devices. I don't know how or why but it's hard to argue with results.

I bought this pretty much knowing it was a scam, but I wanted to have the product in hand before giving a review. First thing I notice is that it is not UL listed. Yikes. That means if this thing catches fire and burns your house down, insurance won't pay out. Also notice it's quite lightweight. Big spark upon plugging it in, so that lack of UL certification is looking real good right now. It made no noise, a faint burning smell, and the LED on the front faintly lit up. So I unplugged it and decided it's time to open it up and see this groundbreaking technology they talk about in the listing. Luckily there is a screw under the sticker on the back, making opening the device easy. No surprise to me, there is no components inside that would do anything to change your electric bill. There is some basic components to step 120v down to run the LED light on the front and that's it. So in conclusion, confirmed scam, they are selling you a bulky dim night light and lying to you. It also is not safe, and if it starts a fire your insurance will not cover the damages due to a lack of valid UL certification. I will return this item now to get my money back.

These work great I've had 20 of them for 3 years now

Easy to use.

My electric bill went from 1200 to about $500 with a couple months

No noticeable difference.

Very good product to buy to save $$$ on electricity

I have put one of these on every appliance, tv, battery charger, anything that needs electricity. My bills went from around $100 a month to $40 a month. This is legitimate!
