### ⭐⭐⭐⭐⭐ Very Useful Tool
*by A***N on 2 October 2013*

This is a must have tool for anyone who fault finds in an engineering environment. It lights when close to a magnetic field, so when for instance a pneumatic or hydraulic valve or electrical contactor/relay energises it will light. very basic/simple, but so helpful when trying to trace faults. Don't confuse it with a volt-stick - Its much more useful.

### ⭐⭐⭐⭐⭐ Great item
*by J***N on 15 May 2016*

Quality item just watch out for the prices you can get them for around £11.That is a genuine one at that price I got stung on here.

### ⭐ Faulty product
*by S***D on 4 December 2018*

Never used product tried it out yesterday for the 1st time and the light stayed a solid red light indication of magnet field working but nowhere near any magnetic fields etcTried again this morning same thing again solid lightFaulty product
