I have arthritis from old injuries in my hands and it is difficult to hold down the button and move the tester around at the same time. Because of that it was difficult to get the light to stay on. However. It served it’s purpose and was helpful, but the design is bad. You shouldn’t have to hold down a button that hard, which is very uncomfortable. I’’m excited to see what grounding can do for my health.

Works and arrived quickly.

it says I’m grounded in tile floor, my bed mat is grounded when it’s not plugged in. Def not reliable.

Easy to use. Let me know my earthing pad is working

When testing my grounding mat with this I discover neither ground plug in one receptacle works!!!

I have several grounding pads and a sheet and have gifted many as they really have helped take away the pain in my knees from sprains in the past. But i always wonder if some of them are working or not. This tester was so easy to work and gave me confidence they are really grounded. Thanks for making such a great product available!

The light broke within the first 5 minutes and the product doesnt test specifically for grounding. It only tests for electrical conductivity. So it will show any living being as grounded regardless of whether they are. What it is really just showing is electrical conductivity. Therefore, even though I know my bed is grounded, I cant tell if Im grounded with a sheet between myself and the mat.

It is hard to press the button to get the proper reading.
