I got this because our electricity meter is in the cellar and we were getting ridiculous bills of £300 per quarter I wanted to know where the electric is getting used.
Installing this was very easy, one device clips over one of the big gray wires coming from the meter. And the display I put underneath the TV. The distance is something like 25 meters and it works fine. Setting the device up is a little complicated due to the way the menu works linking the two sender and receiver however is easy. But once this is set-up its quite impressive. I set it to show the total amount used for the quarter and you can see the bill in monetary terms slowly increasing.
I also set the big display at the top to show the cost of what is currently being used at that moment. So if I switch any device on, or switch anything off, from the TV to lights to kettles, the monetary value is instantly shown of how much is being used now. The biggest benefit it offers is to know how much each device is using and how much they use whilst they are in standby compared to being completely switched off. The device pays for itself and I was sceptical at first, but I thought anything that helps me to monitor and reduce bills is surely a good thing. Which it definitely is and will easily pay for itself.

Having purchased this product, I was a little apprehensive about connecting it to the electricity supply meter. However, a quick phone call to the Ethical Superstore where I spoke to a very helpful member of staff, was very reassuring. The connection was simplicity itself.
The results were initially quite frightening when we saw just how much electricity we were using on individual appliances, especially lighting.
My wife and I therefore made, and are still making, every effort to reduce the electricity useage in our home. I am convinced that before too long, the appliance will have paid for itself in reduced electricity useage, and therefore costs.
I strongly recommend this product with no reservations whatsoever.

This product does what it says on the tin. It's easy to install, the instructions are clear and easy to follow and I've found it very useful in calculating my electricity usage. Good value for money.

We bought this, or rather i bought this and its been sitting on the shelf trheatening my husband for the last few months! he was reluctant to fit the OWL i think he was convinced that it was complicated and so the task was put off for a long time. the other weekend one of the boyssaid when you say electricity costs and we are always being told to switch things off, welllll how much? It was a very good question and we were pushed into fiting the OWL. since that day we have all been enthralled at the amounts different items cost us. I highly recommend it as I am confident that we will save money in the long run and make the family in general more aware of the impact of them leaving lights on and in general using electricity.

I've wanted one of these for ages - finally treated myself and so glad I did. Intuitively simple to set up, works with economy 7 via simple programmable 4 phase and time settings - bit like a central heating programmer. My husband, who couldn't have cared less how many lights were on, now gazes at it in fascination asking me to turn on various appliances! You can see what you are using in pence at any one time or per day, the previous day/week/quarter/year with simple button presses. You can use the default settings or programme in your own utility costs. We have instantly seen that the high usages in our house are NOT actually most lightbulbs, or the TV, computer/chargers etc although obviously they have a cumulative trickle - its anyhting that produces heat, therefore irons, kettles, ovens whack up to something like 20p an hour, and halogen lightbulbs run about 7p an hour for the 6 in our kitchen which tended to be left on before!

Mr asked this question on 26th Dec 2008

Q: The previous version was compatable with economy 7 because you could set the unit cost to match the time periods. However, my electricity tariff charges one rate for the first 225 units and another rate for units above 225. The previous version of the Owl could not differentiate between the number of units used. Can the new version???

A: On asking the manufacturer your question I received the following answer;

“OWL can be set to cater for up to four daily time-switched tariffs, such as is the case with economy 7.

What you are referring to is a tiered payment plan, rather than separate tariffs. This is a common misunderstanding and it is not possible to set OWL up to cater for this, because it is not possible to know at which point in time the higher tier starts. To overcome this most people set the cost rate to a figure just a little higher than the lower tier (maybe by 1 or 1.5 pence) and that will give a reasonable approximation.

Don’t forget that OWL is sold as an educational tool to help people change usage habits by observing the comparative readings as changes are made. It is not a calibrated instrument or an alternative to the domestic meter.”

I hope this helps.
