Review on Revolutionize Energy Monitoring with Blue Line Innovations BLI 24000 PowerCost BLI-24000 by James Smith

I bought this and it only worked for about 1 week and then a big ice storm hit in 2009. We had no power for 10 days so I didn't have much time to use it but it's a great device. In this case you can observe how the measuring disc rotates faster or slower each time you switch it on. Allows you to keep track of which elements use the most energy. It also has an external thermometer that lets you know the temperature first thing in the morning. Just like keeping an eye on your car's speedometer, only better, it helps you keep an eye on your speedometer. your electricity bill!
