## Description

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 : desertcart.co.uk: DIY & Tools

Review: 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.
Review: Look no further, the best value and quality - Great value and very good quality and functionality. Surprised in fact how good it is considering competing testers costing much more.

### ⭐⭐⭐⭐ Good value
*by M***J on 27 January 2026*

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.
