I like mine. It was interesting to see how much current my amplifiers use just idling and how loud I had to turn it up before the power usage increased. And it had to be loud for a while before the power usage would increase. I'm guessing that the power supply caps took a while to run down.
After trying the meter on many things in my house, it seems that electrical items usually use less than the watts stated on their electrical labels. I don't remember the accuracy specs for the meter, but it seemed like it wouldn't be more than cents difference on your electrical bill for most things.
