hoogaGrounding Tester, Continuity Tester for Grounding Mats, Sheets, Pads, Blankets, Pillow Cases. Universal 15 Foot Grounding Cord. Use to Test Effectiveness of Earth Connected Products.

Short version: This tester works well when properly connected. Connecting the pad and the tester to grounding pins of electrical sockets tests continuity from the pad to the tester but does not verify earth grounding. The diagram in the instructions shows both the pad and the tester connected to "E", which is the earth. Most modern houses have their electrical panel connected to earth ground, but unless that can be verified there is no "proof" that the pad is "earthed".Long version: My wife got a grounding pad as a gift and uses it regularly. I got interested in the concept and began wondering how one could verify if it was actually working. I do not mean if the health claims are accurate, but only if it is indeed connecting the user to earth ground. So, I bought this tester. It is simple to connect and operate, but to verify earth grounding it has to be properly connected.Most modern homes are required to have their electrical system connected to earth ground, so this will not be a problem for most. However, can we be 100% sure, especially in older re-wired homes, the contractor connected it to earth ground, the inspector approved it, and that the connection point has not become corroded or totally disconnected?I have a separate copper ground rod driven 6' into the ground outside my window. I connected the pad to the grounded socket and the tester to the ground rod outside my window and the test showed continuity. The only way that can happen is if the grounding pad is indeed "earthed". If you do not have a ground rod available you can connect the tester to copper pipes that go underground.

I just wanted to make sure that this mat was actually grounding me so I bought this tester. It works great as long as you connect it to the outlet protector as shown in the picture. Didn’t work otherwise.I was almost about to return this product, but then decided to test it this way, and I’m so glad I did because now I am 100% confident that my product has continuity. Now I just have to wait for my sheet to arrive and I will be able to test this on the sheets as well. 👍🏻

Simple and effective. I tested it inside and outside on various items. I found that my socks conduct well outside. I also found that my so-called grounding shoes don't ground/conduct at all! I have a grounded pillow case that works great, and I got a new set of sheets that are silver impregnated, and they do not conduct. When buying earthing or grounding items, use this to test!

After purchasing grounding sheets I wanted to be sure they were grounded. This tester was easy to use and not to expensive. I didn't know that you should occasionally check that they test as being grounded.

I purchased one to test my multiple mats. It worked for the first couple of days; after that, the green light only came on briefly showing that the battery of the tester was working —also meaning that whatever mat being tested has stopped being grounded. If the green light STAYS on while testing a mat, it means it’s registering electron flow in the mat. Either the tester (probably too poorly made) is malfunctioning or the SIX mats I purchased all stopped working. I think it’s the cheesy tester. I returned it and ordered 2 more, the 2nd one for backup. Received the other 2 astoundingly quick (next day) - but neither worked. I’m planning to buy a more expensive continuity tester. In the meantime, I’ve been using the mats (situated at my favorite places in the house), and I believe my sleep has improved and I have more energy to tackle a bunch of summer projects that kicked off soon after I got the mats.

I have two grounding mats, both of those were tested as working properly. I also have a grounding pillowcase which no matter where I touched it. It said it was not working. And I just purchased a $90 pair of grounding shoes and the first thing I did was test them. The shoes do not work as claimed so they will be returned. So this isn’t something I’ll be using all the time, I will use it since it works to detect when a grounding product has stopped working. It also is saving me $90 on a pair of shoes that don’t work.

I wanted to have a tester to check some grounding shoes I am planning to buy. Instructions are a bit convoluted, so I watched a few videos that were posted here on this product site and I learned how to do it. I first tried sticking the ground lead in semi wet soft soil with tall grass and it did not work. Then I found an area where the grass was very short and the soil underneath it was a bit harder. I tested it barefoot and the light came on and stayed on; I put my flip-flops on and the light did not stay one. Now I need to find a pair of 11.5 wide grounding shoes to buy. I tried Harmony 783 grounding shoes but not only are they narrow but they also run a few sizes too small.

Tested it in the soil with and without shoes; device lit up when barefoot in the grass. Tested grounsing mat plugged in and did the same. Glad it worked. Easy to use and confirm my mat is working.
