5.0 out of 5 stars Extremely useful - should pay for itself, 17 Mar 2009
This review is from: Plug-In Power and Energy Monitor (DIY & Tools)
I bought one of these in response to a £210 per quarter electricity bill in December 2008. I've just received my March 2009 quarterly bill - £140!

Initially it's somewhat addictive, running round trying to work out what's using all the power. In my case it was my computers - just turning the things off when I'm not using them made the bulk of the difference to my power consumption. The way the washing machine was using power was a revelation too.

Equally interesting was what doesn't use power. We're repeatedly told not to leave TVs, etc., on standby overnight. Well for my LCD TV and Sky box, switching them off at the switch, instead of leaving them in standby saves so little power this device can't measure it. Their standby setting, waiting for the remote control, is clearly very efficiently implemented in the electronics.

But here's one I bet you haven't thought of: games on your PC. Starting a game on my PC makes it draw 84W more power than when it's doing more normal stuff. All those transistors on the graphics card spring into life and use up as much power as a very bright lightbulb! The days of me leaving the game in pause mode when I wander off to do something else are over!

Technically it's a great device, as others have said. What's interesting about it is the way it gives you information you can use. Mine paid for itself within a month.
