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.

Just got it today and tested it out. It worked fine for me even though reading other reviews had different experience. I did notice that the light came on when I didn't make contact with the grounding sheet but the light went out after a few seconds. The instruction sheet explains that if the light goes off after a few seconds then you are not grounded but this light is also a test for the batteries strength. Very important to follow the instructions! I did test when my sheet was plugged into the grounding outlet and when it was not. The reader worked both times. Price is good too! Hopefully this gadget will still work for me in the long run.
