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.

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

Excellent piece of kit. LCD display is invaluable as it shows voltage being delivered (amongst other readings) so you can check appliances are receiving Indicated L/G reverse, but the fault was actually missing G. L/G reverse is a common indication though for this fault, but I knew this and located the missing G on the circuit. Would give 5 stars but as others have said the LED configuration for CORRECT socket wiring is just the 2 left hand LEDs, so you're not sure if the 3rd LED might be faulty (all 3 LEDS lit = L/V reverse + missing GRD).

Very Good works well .....

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

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.

Having re-wired an extension lead myself, I thought it prudent to check that it was safe to use. This product confirmed that I had carried out that task correctly and it will be useful item to have for future similar tasks. Not too expensive either. Another use will be to determine the voltage of our mains supply. (We live in a village). Sometimes our lights seem a bit dim and the kettle is slower to boil. Just plug this in and the voltage is shown instantly.
