PR10-F TFT LCD Screen UK13A Socket Power Meter Monitor Plug Energy Meter Watt AC Electrical Tester Usage Monitor

Very good value, very informative, tested and seems reasonably accurate too. Can interfere with the socket switch, but this depends on socket.

Lovely display but the awful design of this unit means that it is unusable in a switched socket. The back of the case sits flush against the socket preventing you from switching it on.

Great product that works well and shows acurate reading in UK...which almost all others do not becasue they don't offer enough decimal points.

Nice display, lots of features - one major problem; if you plug it into a standard UK double-gang switched socket, the plastic on the back is not cut out sufficiently; the 'shoulders' of the device stick out over the switch whichever side you use - so it turns the socket off (or more precisely, presses on the switch so it lies "flat") when you plug it in - rendering it useless! Works fine ONLY on extension leads or UN-SWITCHED sockets - be warned!
