Funciona bien

Item came broken, never did work

I could not tell if the device was working correctly. The device indicated that all my home interior sockets are not grounded. There were no trouble shooting suggestions

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.

I contacted seller, who answered promptly, but not entirely coherently. But I was able to figure it out. So here is how you set it up. You have your grounded item, long black cord snapped onto item, and running (most likely) to wall outlet, where its plugged into the thingy that plugs into the outlet. So you plug the long black cord that comes with this device into the other available hole. Snap the other end onto the device. (Im assuming youve already found where it says press, and made sure the little green light comes on for a second.) Place the big silver metal button on the back on your mat or whatever, press and hold - and if you are properly grounded, the light will come on and stay on for a few seconds. Yay! Your product works! You can check it by holding it off the mat, or whatever, and pressing again - the little green light will come on for a moment and go right out, just as it did when you checked it. So there you are, peace of mind.

Muy fácil para medir , yo había comprado otros y eran muy difíciles de usar. Muy buena compra

Product is not as advertised. Product is very small and flimsy, its like a toy. I wouldnt even want it for free. The advertised product is all white, with a WHITE earthing cord. But I received a thick, chunky BLACK earthing cord instead of a white one as was advertised. It was poorly packaged, wrapped in bubble wrap and put in a zip lock bag, etc. I called Amazon and requested a refund.

Its working the ways it works

I bought this to test the concrete around my house and my grounding sheet. It works. Now I know that when it rains I can sit on the patio and still ground.
