Grounding Patches and the Testers That Prove Your Setup Works

Two very different kinds of gear share this page. Patches are a speculative, targeted way to ground one sore spot. Testers are the boring, essential tools that prove any of your grounding actually works. If you only buy one thing off this page, buy a tester. It is the cheapest item and the one that keeps you honest.
Testers: Buy These First
This is the least glamorous $10 you can spend on grounding, and the most important. A grounding mat or sheet connected to an ungrounded outlet does nothing. These two tools settle whether your setup is real. The full walkthrough is on how to test your grounding.
Outlet tester (Klein RT110)
Price: $9.97 (verified August 2026)
Does: confirms your outlet is correctly wired with a real ground
Best for: everyone grounding through a wall outlet
Plug it in, read the lights against the legend. If it does not show a correctly wired ground, that outlet is useless for grounding and worth fixing anyway. The Klein RT110 is under ten dollars and is the cheapest honest thing you can buy in this entire category. If you also want the GFCI trip test, the Klein RT210 is about $14. Either one does the job. Every grounding household should own one.
Check current priceContinuity tester or basic multimeter
Price: often included in grounding kits; standalone multimeters from about $15
Does: confirms the mat or sheet actually connects to ground
Best for: verifying gear on day one and retesting sheets over time
Hooga sells a purpose-built continuity tester for exactly this, and the Earthing Universal Mat Kit bundles an outlet checker. If yours did not, a $15 multimeter set to ohms tells you whether the conductive surface connects to ground with low resistance. This is how you catch a washed-out sheet or a dead cord before you waste weeks grounding to nothing.
See the purpose-built grounding testerHooga sells direct and offers HSA/FSA checkout through TrueMed, which can mean paying with pre-tax dollars if you qualify. How that works, and when it is not worth it.
Grounding Patches: The Speculative One
Patches are sticky conductive gel pads you place on a specific spot, a sore knee or heel, and wire to ground. The idea is targeted contact on the area that hurts. Be honest with yourself here: this is the most anecdotal use of grounding, with the least research behind it. Treat it as an experiment on one body part, not a treatment.
Groundology grounding patch kit
Price: $42.39 for the kit, 30 patches plus cord and North American plug. Replacement packs of 30 are $25.17 (verified October 2026)
Includes: 30 adhesive gel patches, a coiled cord (6 ft, stretches to about 20 ft), and a grounding plug for your country
You also need: an outlet tester, if you do not already own one
Ships from: the UK. Cheapest US option is $15.29 by tracked Royal Mail with import taxes prepaid, 6 to 7 working days, so about $58 delivered. Charged in pounds (verified October 2026)
Best for: people who want an established grounding brand's patches rather than an unbranded pack
Note, October 2026: Earthing, Clint Ober's brand, has stopped selling patches. This card used to recommend its refill packs at $29.99 for 90. Earthing.com's patch collection is now empty, the old product pages either 404 or bounce to the homepage, and Earthing's Amazon storefront carries no patches either. We already corrected this card once in August, when Earthing's bundled patch kit disappeared. Now the refills are gone too.
Groundology is the replacement. It is a UK grounding company that sells its own line next to Earthing-branded gear. The patches are the same ECG-style gel pads, 2 by 1 inches, and unlike the old Earthing refills, the kit ships with the cord you need to use them.
Know the trade before you buy. You get fewer patches for more money. Earthing's refills worked out to about 33 cents a patch. Groundology's replacement packs run about 84 cents. The patches are sold as single-use, though Groundology says each one survives a few reuses if you peel it off carefully and store it on plastic. And the order ships from Britain. The cheapest US delivery is $15.29 with import taxes prepaid, which puts the kit at about $58 at your door and a week away. Groundology also charges in pounds, so check whether your card adds a foreign transaction fee. If you just want to find out whether patches do anything for you, the generic pack below is cheaper. Buy this one if the brand matters to you.
Check current priceThis link goes straight to Groundology and we earn nothing if you buy from it. We are not in any program with them. Groundology also says its official distributors are not allowed to sell on Amazon or eBay, so a "Groundology" listing there is unlikely to be genuine.
Generic conductive gel patches
Price: about $27 for a 10-pack that includes a cord and adapter (verified October 2026)
Includes: reusable adhesive gel pads, a grounding cord, and a wall adapter
Best for: a cheap first try, because this is the version that comes with the cord
This pack ships with the cord and adapter, and at about $27 it is the cheapest way to find out whether patches do anything for you. You get 10 patches against Groundology's 30, so you pay more per patch, but a first experiment rarely needs 30. If you are trying patches for the first time, start here.
Just remember the patches are only as good as the ground they connect to. A patch wired to an ungrounded outlet is a sticker.
Check current priceHonest Priority Order
If you are shopping this whole niche for the first time: outlet tester first ($10), then a $25 mat, then, only if the mat earns it, a sheet. Patches are a later, optional experiment. Spend the least until grounding proves it does something for you, because the evidence has not proven it does something for everyone.
