Grounding Continuity Tester for Grounded Products, Mats, Sheets, Pads, Wrist Bands, Blankets, Pillow Case. Universal. 15 Foot Cord Included. Use to Test Effectiveness of Earth Connected Products.

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.

Very simple. Works perfect.

The instructions leave a lot to be desired.

I liked it being fitted , I have a handy cap that causes extra effort to make a bed.

The Tester continuity green light comes on every item (air, rug, skin, etc.) in addition to the mat. It does not last for 3 seconds as instructions explained. Therefore, I think this Tester is defective.

Works great for grounding locations

The tester is very easy to use and immediately lets you know if your earthing product is grounded. I have several earthing mats and an earthing mattress pad, and I test all the mats every day to make sure there is always continuity. Using this tester, I found one of my mats was showing no continuity, so with further investigation, it turned out to be a faulty cord. Once the cord was replaced, the mat tested with perfect continuity. The tester is essential for all earthing products. Highly recommend.

I was excited to get the tester. However, it seems to be a button that flash a green light. Even when I unplugged it from the socket and pressed the button, the light still came on. I’m not sure it is testing anything.

I was so excited to test my grounding mat, but this tester won’t work. Not sure why but returning it with disappointment.

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.
