– Socket Tester RCD Plug Outlet Tester, Electrical Receptacle Detector with LCD Display, 90-250V Power Socket Automatic Electric Circuit Polarity Voltage Detector Plug Breaker Finder

I was a little sceptical at first as it is quite a cheap item, but upon receiving this, I have to say it does its job well and is a well built product. I used this to check a few plugs in a newly built shed and kitchen. It did find one fault where a neutral had come loose when refitting the sockets after decorating and was fixed and tested again for a correct sign from the device. It's easy to read and even easier to use. The RCD test button is a nice touch allowing me to make sure that if my shed sockets should get overloaded that the consumer unit fitted will do its job and trip off.

Bought this after reading UK voltages were dropping below the 240v we've come to expect (curiosity really). This is a great little device to have plugged into your ring-main, I switch it on occasionally, this morning it was reading 251v and thankfully, no fault with my wiring (peace of mind). Great value for the price and well made. Recommended.

This seems to work well and is a useful item to have in your kit. One small criticism, the LCD display can only be read if your head is on the same level as the device. Sockets are quite often a foot or so from the floor so you have to get your head to that level to read it.

Very Good works well .....

Very easy to use and provides some really good helpful information on the voltage from the socket.

Very good tool for the electrical trade. Clear LED reading, showing the required voltage within the parameters. And speedy fault diagnosis.

Very good and easy to use

Simple to read and used to identify a serious electrical fault.. enabled me to report problem to a qualified electrician for repair. A must have purchase for your toolbox.
