Review on 💡 Power Save Energy Saver - Electric Smart Device for Household Office Market, US Plug 90V-250V 30KW by Mark Gancio

Terrible hardware. With ONE or 2 sockets, you can't use it. Many energy saving devices contain the element itself, which must be connected to the device. EVEN IF it saves electricity, from a functional point of view you will only know if the savings actually reduce consumption when you look at your electricity bill. I bought two and immediately saw that in most cases they are NOT useful so I have to return them. It's cheaper than other "power savers" but it's useless from a functional point of view. It must have a built-in outlet for the device you're trying to use to lower your electricity bills.
