Review on Efergy 4 0 Wireless Electricity Monitor by Yuan Walsh

I used this to track where my electricity bills are going and it's easy to spot when you look at the watt-hours you're using. The numbers tell the story! You can turn the lights, computers, TVs, etc. on and off and see how much something draws. How accurate is that? Well, I don't have any scientific testing, but from my rough calculation of the number of bulbs installed and when I switch something on and off, it seems very accurate and at least takes some getting used to reducing energy use in your home. As a side note, if I accidentally leave something on and go to bed and see that my house's current at night is greater than the standby current (ca then I go hunting to turn it off. It made me very aware of what was being drawn , so don't take this if you're mildly obsessed or a nerd like me. It definitely saves me money even though I just skip appliances and lights that I've always left on. Definitely worth it.
