Where the layers disagree ⚡
4 CONTRADICTIONS DETECTEDVIDEO content demonstrates the technique confidently, but USER comments on those same videos report pain, pulsation, and a panicked heartbeat sensation — signaling a safety/expectations gap the videos do not address.
USER reports the brand's paid courses, Roll Model book, and 30+ videos do not answer whether feeling a strong heartbeat through the ball is normal — exposing a documentation gap between BRAND content volume and USER unanswered questions.
USER questions like 'Where to get the coregeous ball?' and 'Can we use other type of ball?' suggest discoverability and substitutes are real concerns, but no VIDEO or (missing) BRAND layer provides comparison or purchasing clarity.
Only USER and VIDEO layers are populated; BRAND claims and INTERNET expert reviews are absent, so any statement about quality, materials, or medical safety cannot be cross-validated.
