Very good product for better understanding the energy usage of your plug in products. It couldn't be simpler to use with very straightforward instructions. Just enter your Kilowatts per Hour price for electricity - this is your standard price of electricity available from your bill (in my case 8.5p). The meter will remember this price even when unplugged. Now go around the house plugging things into the meter. You can quickly see the real difference in boiling a full kettle versus just enough for one cup. It will show the power (Watts) being used and how much energy (KWHs) was used over a period - e.g. to boil the kettle.

I was also interested to see how much my microwave is using even when it isn't cooking!

My freeview personal video recorder uses almost as much in standby as when switched on. I've decided it will be switched off off most nights (I can cope with the fortnightly programme guide being updated just once a week).

A good way of raising energy awareness within the family.
