### ⭐⭐⭐⭐⭐ Invaluable when you need it, not the best one out there
*by C***T on 18 June 2020*

At first I was not terribly impressed, thought I had wasted my money. However a few months down the line and it went from waste of money to being gold plated and fantastic. A real life saver. I am an gas engine engineer and had to trace 2 core wire out of a electrical control cabinet in a bundle of 15 wires, down conduit, where it then split into 4 different conduit going all over the engine, we are talking a 30ft x 10ft x 8ft (LxHxW) engine all cable tied together. An impossible task, but this little cheap plastic green tone generator did it, I was so thankful. I would not have been able to do it without this. I identified the cable, checked continuity and it was spot on. Fantastic. I can’t praise this enough today, it has earned its place in my van and it’s now a valuable bit of kit for electrical fault finding and tracing wires
