Easy to Use
Arrived quickly. The device works perfectly, no issues. I didn't even have to read the instructions...but I did anyway. Cheers.

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.

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!!
