Review: Happy and Safe Now - Works well and the one I received was green and triangular not like the photo of a grey square one on desertcart, apparently I now have the new 2026 model, which is nice. so I tested a socket in my living room and it showed a fault, when I opened the socket the live and neutral were reversed, it has been like that since the house was rewired in 1986 ! So I have now tested them all. Really useful tool, small and compact and the sound is loud but not too annoying. Happy !

### ⭐⭐⭐⭐⭐ Excellent little device, if you have any three pin electrical sockets.
*by T***N on 6 January 2026*

I love this little device. I’m not a professional electrician, just a home gamer so I don’t have bags full of testing equipment. This came in handy when one side of a twin socket started playing up, initially working intermittently and then failing completely. This showed a faulty connection and on examination ⚠️ (mains isolated first!!) ⚠️ it turned out the bus bar bridging the two sockets had burnt out (later traced back to a faulty kettle). New socket installed and tested. Didn’t work. 🫣 rather than panic I plugged this little tester in and found that the neutral wire had pulled out of the terminal while wrestling with the re-fitting of the new socket. Wiring sorted I plugged it back in and it worked fine. The audible beep (and lack thereof when no power is reaching it) was a good indication that I’d isolated the right circuit at the consumer unit. (If in doubt turn the whole supply off!). As a ray to use diagnostic tool for professional electricians and avid home gamers alike, this is invaluable to have in your tool bag. It’s a lot less intimidating for noobs than the rather dubious practice of poking multimeters or continuity testers into the plug terminals. We grow up being told NEVER to poke anything into plugs, and only those foolhardy enough to ignore this advice grow up to become electricians! Once you’ve used it for a specific job, you will then run around the house testing every socket, and when all sockets are checked, you will go door to door offering to check your neighbours’ sockets 😄
