A Classic Tester which works very well
Martindale testers have been around for decades, are simple to use and reliable. I quickly found out some of my sockets had live and neutral reversed - so much for professional installers!!

simple to use
This is simple to use ,but once you have checked the outlets in the house that will be the end of its usefulness You will then lend it out to someone else , after the second time it will be lost to you for good .

Does all you need it to.
Perfect for work as an electrician. Always bemuses me though the price for the sake of a buzzer compared to those without. Only reason it’s not 5 stars.
