I'd award it 6 stars if I could...,
This review is from: Belkin Energy Saving Insight Energy Cost Monitor (Personal Computers)
Intuitive & easy to use, this gizmo's paid for itself within 3 days of purchase.
Its large & clear display on the end of a long roaming cable makes it particularly suitable for the monitoring of power from awkwardly-placed power sockets such as those just above a skirting board and behind a waterbed. No comment, please, on the fact that I have more than one of these beasts but it was interesting to learn that each consumes power at the rate of £95 to £110 per annum: doing so has prompted me to think about turning down the rheostats and improving insulation of two that are not in permanent use. Perhaps of more relevance to most people, the same cable allowed me to check the power of an 8 cu ft fridge/freezer (graded A in the EU's energy scale when I bought it new in 2006): this, I found, has been adding more than £170 to my annual bill. Replacing this energy gobbler with an A+++ graded fridge/freezer will save at least £150pa in coming years.
Everyone who pays an electricity bill should have an energy consumption monitor such as this. If you haven't got something of the sort already, buy one now - you won't regret it!

Your saving estimate is too happy. Go to Wikipedia and look up the EU rating system. An A Grade means less than 55 kW hr per year and A+++ means less than 22 kW hr. So the difference is about half. Your £170 per year spending is likely to be wrong since a A+++ f/f uses about £20 in electricity so your Rating A f/f should be using about £50-£60 per year: either there is something wrong with the use of the fridge/freezer or you are not averaging the readings from the Belkin energy monitor over a long period of time taking seasonal effects.
