Pros: This product does everything it says it does. It accurately measures all sorts of electrical characteristics, the most useful to be being wattage. Sturdy, no apparent problems. The price is right, too.

Cons: Only one small thing, is that when plugged into a standard wall socket, it does not leave room for something to be plugged into the other adjacent socket. Not really a problem.

Overall Review: I believe the documentation said it can take statistical measurements, however I have yet to figure out how. I can see that it does instantaneous measurement, which is fine for me.
