"Great price, good performance. Only reason I have marked it down on performance is that there's a fairly well known issue with BG RCD's giving high loop impedance readings compared with other brands. e.g. this one may read 0.5 ohm higher than say a wylex in the same circuit. Apparently BG are aware of this. My only advice is to return such a unit for exchange, and BE SURE TO PROPERLY TEST after installation (and I with a proper loop tester, NOT the button). Otherwise, great products at great prices. There are arguments that with the reg's, the RCD will allow much higher readings anyway, but I would say that Wylex, MK, BG etc should all offer similar impedance in the same circuit. Still recommended to buy. Rick."
"Firstly, my local Screwfix was the only place to have one of these in stuck on the day it was needed. Secondly, it was slightly cheaper than the competition would have charged. Thirdly, it worked as advertised and cured an intermittent fault which had been hard to trace. Excellent!"
