Title: Very useful device that will pay for itself
Product review: I bought one one for my parents and they are having fun finding what appliances are power hogs and whats not. The discovered that one of their freezers was staying on all the time causing it to draw lots of power. They had the unit serviced and not its great. I have also been using it to find out how efficient my appliances are. I discovered an older refrigerator I got when I bought is costing me some money so I will be replacing it soon.
