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

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.

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.

It worked just as described.

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

Absolutely useless for the designed purpose. It tests conductivity just fine. But it will not indicate if your grounding product is actually grounded. It lights up even when disconnected.

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.

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.

work like it was suppose to

Works for grounded sheets, but I retuned because the sheets came with one

I live in UK. I bought this pen to check my grounding fitted sheet it works really well and easy to use. It gave me reassurance that it is still working well

The pen doesn’t work. At all Useless purchase

Bought for testing a grounding mat, works well

Worked exactly as described.
