Second is a mains monitor.

It's a true power meter, also reading out voltage, current,
power factor, frequency, energy, and possibly something else
I've forgotten.

Seems to do what it says on the box and cheaper than others I've seen at
17.57.

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.
