"if you have got valuable electric equipment to protect like a TV, dvd, etc. inside or outside Always protect it from a energy spike and prevent it from crashing or worse. Get a master plug RCD Adaptor"
"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."
"Bought my third one to use on my external extension cables for the garden & garage. Whilst I find they work when they have to, I still worry about the heat they generate. No other adaptor I use internally gets anywhere near the heat level. I have used them for over 10 years, so overall I'm happy that it will save me when needed. PS Please do test on a regular basis."
"Great RCD, feels like good build quality. I bought my last one some 10 years ago from a national hardware store and from memory this one was still a couple of quid cheaper. No idea on relability as only just bought it."
"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."
