30000W Electricity Saving Box Intellegent Electric Power Saver Energy Saving, Suitable for Air-conditioners, Refrigerators, etc

I have a 3,000 square foot home. It's recommended that you use one of these units for every 1,000 square feet. For the first half of the month, I did just that, then, for the second half, I added four more units which is one unit for every 300 square feet. If these units work at all, I should have seen some savings, but I didn't, my electric bill for the month was exactly what I would have expected it to be if I hadn't been using anything at all, That said, I've definitely noticed that my appliances are running more smoothly and efficiently. These units are advertised from China as simply spike protection, and they certainly do that, in fact, I've noticed a difference in the feel of the electrical environment and suspect that it's healthier for people and animals. They have representational graphs of the spiked wave of a conventional current vs the gently curved wave of current that has been adjusted with these devices. So, if all you care about is saving money, these should help with longer appliance life, and if you're concerned about health issues, I suspect that they'll help in that respect also. I know that I,m experiencing a greater sense of calm since I installed them.

Works great

My electric meter turns noticeably slower, can't wait to get the next electric bill

I was quite dubious when I ordered this device. But after three months of use, I can highly recommend it. Our electric usage has been 28

I plugged it in and is it working? I don't know. I can't tell from the power bill. It did not drop in half that's for sure. If it dropped at all it is only by a couple of dollars.I tell myself if this is less than I would have paid then I am glad I got it. But do I know for sure? No.

There was no change in my services AND I returned the product and it's been nearly a month and I still haven't received my refund.

I purchase three other energy savors device's it seems to be working. This one is for the freezer i hoping ut works.

Unbelievable cut my bill in half, great product

No funciona, no ahorra ni un kilowatt, no gastes tiempo el dinero te lo regresa Amazon si lo devuelves a tiempo.

This product is clearly a Return. They used same packaging and the actual Power saver logo is already scratched.There is no point to even try it out.
