I tried mine yesterday for the first time. I dind't have it plugged in very long, about an hour. I, therefore didn't notice much difference. What I did notice was when I unplugged it. What an arc. It looked like fireworks. I understand that these things pull like 1000 watts. That is just short of a hair dryer. So I don't plan to keep mine on too long, maybe three hours with a timer. It will have to be a heavy duty timer to carry the load.
