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.

Does indicate when it’s working.

Good product but different cable color as in picture

We like the mat but they forgot to pack the electric cord that hooks it up.

It proved mats dont work if covered with a sheet, even a very thin one!

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.

No complaints. Worked jus fine

Works great for grounding locations

This is a vital part of staying grounded. So you bought a grounding mat and plugged it in. Cool, but how do you know its working? Test!

A great tool to see if youre grounding products are conducting properly.

My earthing products have no lights or indicators so it is nice to be able to periodically make sure they are in good working order with this tester.
