Who should buy which
Family offices with multiple longevity-focused members. Private trainers / coaches serving HNW clients. Buyers who specifically want the gold-standard measurement quality, not the wearable-estimated version.
You only need 1-2 VO2 measurements per year (use a clinic). You don't want B2B-tier purchasing complexity (annual calibration contract, occasional service visits).
Clinics, family offices, private practices, high-end coaches. Buyers wanting clinical-grade VO2 measurement without COSMED-tier capital outlay.
You need the academic-research-grade pedigree (go COSMED), or you only need 1-2 tests per year (use a local clinic).
