Conductivity Test Pen, Tester for Earthing, Continuity Tester for Grounding Mats, Sheets, Pads, Socks, Pillow Cases. Use to Test Effectiveness of Earth Connected Products.

I was able to walk with bad knees without any discomfort alter sleeping on the mattress for only one week. My mattress did not come with this particular tester, and I wanted to rule out any chance of a placebo effect. Placebo would have worked for me, but the tester is too easy to use, it is compact and the price was right.

Worked great to test my sheets to see if they need replacing. I have mine plugged into the yard. The sheet snap and lines near the snap lit up but no lights on the majority of sheets. So I know it’s works, it’s just old.

This product is not a grounding sheet tester. it is a continuity tester amd the fact that this false advertizing is on here is horrible. This does NOT test if your grounding sheet is actually connected/grounded properly. Shame on you scanmers.

It arrived as promised and in perfect condition. I used it in my homeschool chemistry class to show ionic solutions conduct electricity as well as any material that is a conductor. The light is good for demonstrations.

This conductivity pin is easy to use. It’s OK Quality. It seems to function. OK great value for the money.

Got this to test my grounding mat. It’s easy to use and lights up when touched to the top side of my mat but not the underside so if the mat goes out I will know by testing it.

Works as intended

It worked properly
