Great item if your unsure of your sockets
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.

This is a great RCD Mains Tester
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.

Cheap easy non invasive check.
Does what it says on the pack, straight forward,easy quick check. Worth the money even as a visual, live / dead indicator.

Great piece of kit for diagnosis of UK domestic socket faults
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).

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

For checking home solar installation.
Works as described in information. Detected an earth issue which now needs investigation.

wrong voltage and RCD indication
The voltage reads way too high compared to my fluke tester The RCD reading is showing 38ma yet the RCD does not trip and it is the 30ma RCD. With these errors |I will send it back.
