"Masterplug RCD Adaptor, allways use a RCD plug if you are using anything outside even for a short time, I would recommend this one Masterplug RCD Adaptor for value and reliability, what price do you put on your families life."
"Works well, tripping faster than the consumer unit RCD. Only reservation is that it runs hot, which probably does not matter as most of these are used only occasionally. Jury still out on long-term reliability."
"Does (hopefully) what it should. Only, slight, criticism is that the orange light (showing that it is working) is too dim to be seen without getting on hands and knees to see at skirting board level."
