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 $25 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 or Sperry GFI6302)
Price: about $10 to $16 (check current price)
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 runs around $10 and the Sperry GFI6302 around $16. 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
Many grounding kits (including Hooga's) bundle a small continuity tester for exactly this. 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.

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.
Clint Ober / Earthing Ground Therapy Patch Kit
Price: around $79 for the 90-patch kit (check current price)
Includes: patches, grounding cords, an outlet checker, and the earthing book
Refills: roughly $19 for 30, $39 for 90
Best for: targeting a specific sore spot with the original brand's kit
The full kit bundles patches, cords, an outlet checker, and Ober's book. It is the most complete patch option and it includes a tester, which is a point in its favor. Cheaper generic patch packs exist on Amazon for $20 to $30, and they are fine if you just want the gel pads and already own a cord and tester. Neither will do much if your outlet is not grounded.
Check current priceGeneric conductive gel patches
Price: about $20 to $30 for a 30-pack (check current price)
Includes: gel patches only, usually no cord or tester
Best for: people who already have a grounding cord and just want more patches
Fine as a refill or a cheap first try if you already own a cord and a tester. Just remember the patches are only as good as the ground they connect to.
Check current priceHonest Priority Order
If you are shopping this whole niche for the first time: outlet tester first ($10 to $16), then a $30 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.
