Lab Tests & Material Verification

DefenderShield states that its shielding technology has been scientifically tested to conduct, absorb, and dissipate up to 99% of EMF emissions from 0–90 GHz, including the full 5G spectrum. On selected products, the brand also refers to independent testing and broad-spectrum coverage across both ELF and RF ranges. Where customers want a personal-use shielding product backed by a strong public-facing shielding claim, this is one of the clearest examples in our range.

WaveWall publishes simpler, consumer-facing shielding figures on selected product pages. The WaveWall Universal Phone Case states that it blocks 85% of mobile phone radiation from reaching the body. The WaveWall Laptop Radiation Shield similarly states that it reduces exposure by 85%, while still allowing normal laptop use, including Wi-Fi and Bluetooth connectivity. These are the clearest public-facing performance figures currently shown for the brand on the site.

YSHIELD provides some of the most technical public documentation in our range. For example, HSF54 shielding paint is presented with published data showing up to 90 dB shielding at 40 GHz, and YSHIELD also provides product data sheets, expert reports, and certification-related documentation for this material. The brand’s documentation states that attenuation testing was carried out from 600 MHz to 40 GHz, and its expert report explains the shielding result in terms of transmission attenuation and shielding effectiveness. For customers looking at room-level or building-level protection, this is the kind of evidence that makes YSHIELD stand out.

Safe and Sound products are different because they are designed to measure exposure, not block it. That means the most important public evidence is not a shielding percentage but technical detail around calibration, operating range, units, and detection capability. On product information available publicly, the brand highlights calibrated RF measurement, practical field use, and specifications designed to help users assess their environment more accurately before making shielding decisions. This makes Safe and Sound especially useful for customers who want to verify conditions rather than rely on assumptions.

Gigahertz Solutions is one of the more specialist measurement brands we stock. Public product documentation for the HFW59D states a 2.4 GHz to 10 GHz frequency range, while related kit documentation notes that the meter extends measurement to real 10 GHz. The published specifications also include measurement range, accuracy figures, and directional antenna details. For customers who want more advanced RF investigation, these published technical details are often more meaningful than simplified consumer claims.

MVG sits firmly in the professional monitoring category. Public documentation for the EME Guard Plus states an operating range of 1 MHz to 40 GHz, use of a triaxial probe for isotropic measurement, and that each device comes with a calibration report. MVG’s public RF safety materials also describe the system as suitable for continuous monitoring, with audio and visual alarms, and compatibility references tied to recognised RF safety frameworks. For customers who need higher-level monitoring capability, MVG provides some of the strongest professional-grade public documentation in our measurement range.

Not every brand should be judged by the same kind of evidence. DefenderShield and WaveWall mainly publish shielding-performance claims for personal-use products. YSHIELD publishes more technical attenuation data, expert reports, and certification-related information for home and building materials. Safe and Sound, Gigahertz Solutions, and MVG focus more on calibration, operating range, sensor design, and measurement capability because they are measurement tools rather than shielding barriers. We think the fairest way to present the evidence is to show each brand in the context of what it is actually designed to do.
