RF Safe argues that while it has operated since 1998 and emphasizes “physics-based” design and education, the broader anti-radiation phone case market is widely criticized for hype and potentially misleading “blocking” claims. The post says some experts consider the category ineffective or even counterproductive, including concerns that poorly designed cases may interfere with antennas and prompt phones to increase transmit power. It positions RF Safe’s QuantaCase/TruthCase as an outlier for transparency and design choices, while noting that independent 2026 testing is limited and some claims rely on demonstrations, older tests, and design critiques.
