EMF Radiation Harmonising Sticker
A zinc-and-copper "harmonising" sticker applied to a device -- a field-modification product, not physical shielding, so it isn't comparable to the BlocSock on a dB or SAR-reduction basis.
DOCUMENTED CAPABILITIES

- Manufacturer
- EMF Protection UK
- Material
- Proprietary zinc and copper alloy matrix (not quartz)
- Mechanism (manufacturer claim)
- Passive field modification -- does not block or attenuate signal
- Coverage
- One sticker per device; multi-packs (3/5/12/20) for whole-home use
- Signal impact
- None claimed -- device connectivity, battery unaffected
Unlike the BlocSock, this doesn't physically block or attenuate a signal: it's a passive zinc-and-copper adhesive sticker applied directly to a phone, router, laptop or other emitting device, which the manufacturer says modifies the character of the device's field rather than blocking it -- so it has no measurable effect on signal, battery or connectivity. One sticker is needed per device; the manufacturer sells multi-packs (3/5/12/20) sized for whole-home use across routers, laptops, smart meters and similar.
What to check
This works on the same unverified "field modification" principle as other EMF harmonizing products EMF Practical has flagged (e.g. Blushield): it does not claim to physically block or reduce measured EMF, has no comparable dB or SAR figure, and its effects have not been independently tested by EMF Practical. If you want a shielding product with a testable metric instead, see the BlocSock case.
Confirm the exact model revision and the measurement conditions that matter to your use. Detection coverage is not a guarantee of uniform accuracy.
