"Apart from its serious safety value this is a great addition to anyones toolbox because if you are as geeky as me you will go round the house touching light switches and sockets to see the detector flash its lights and buzz its buzzer.
This is a great and safe way to detect live circuits without touching bare metal contacts, Simply place the probe on the suspected live wire or near it and the pen will tell you whether it is live or not. Super value"
"Built in light is green?? No use at all.Should be white, a product like this is paramount that it should detect live wires however this one sometimes does and sometimes doesn't even on the same live wire with the brand new batteries installed. this is getting returned asap avoid at all costs"
