Very nice and confirms that the grounding Matt is working..

Works as it’s supposed to. I have used it to check which of my grounding devices actually work, which is most of them apart from one. I have also use it to find which floor surfaces in my home are grounded. So I now know that I can stand on the kitchen floor or the slate fireplace hearth and will be grounded. And just for fun, I have taken it out and about with me to confirm that I am grounded when standing in the garden barefoot, or when wearing boots but touching a tree or any other living plant or grounded person. Also any metal object embedded into the ground, such as a lamppost. Confirmed that concrete is also grounded, but not asphalt. A very useful piece of kit.

It actually works! Easy to use and good value for the price.
