Categories are compared in general terms; individual products vary. Shielding physics is well established, but shielding products are rarely studied as consumer devices, and partial shielding can cause a phone to increase its own transmit power to hold a connection. "?" reflects that most sticker and pendant products make claims that have not been demonstrated in published research. Harmonizing and frequency devices vary widely in their evidence base: some hold patents and cite peer-reviewed studies, others rely on unpublished or non-peer-reviewed testing. Unlike blockers, they do not interfere with signal; unlike Aires, most have not published independently conducted, third-party validation at the same scale.
Real physics, but a blocked phone is an unusable phone. Honest use case: devices in storage.
Vague mechanisms and no published research. Regulators have acted against sellers in this space before.
Legitimate category, uneven evidence. Some brands hold patents and cite real studies; others lean on frameworks not accepted by mainstream science. Worth checking who validated the claims, and how.
Patented, peer-reviewed, and no blocking. Built for the devices you actually use every day.
Over two decades of study, with results in scientific journals rather than kept in-house.
EEG and thermographic studies conducted by third parties, not just the company's own lab.
A patented silicon resonator etched with up to 63 million microscopic conductors in a fractal antenna pattern.
Match your answer below and you're done. Every device uses the same patented technology, they just cover different spaces.

Sticks to the back of your phone, the device you hold closest, longest, every day. The natural starting point.
