It's a true power meter, also reading out voltage, current, power factor, frequency, energy, and possibly something else I've forgotten.
CPC have been offering it in bulk (10 IIRC) for around £11 + VAT.
Maplin have had it on offer in some of their shops for around £12, but it's normally twice that price.
I have a couple. The only issue with this device is that it has no battery backup, so it loses everything if the power goes off. Otherwise, it's very good.
