Who should buy which
Sleep optimizers who've already addressed the foundational variables (dark room, temperature, consistency) and want a low-effort marginal intervention. Practitioners' patients with chronic inflammation or chronic pain.
You haven't optimized the foundational sleep variables yet - grounding is a marginal layer, not a primary intervention. Or you're skeptical of the limited research base and want randomized-controlled-trial evidence (which grounding doesn't have at the depth other interventions do).
Frequent travelers, anyone with light pollution, partners on different schedules, side-sleepers who hate flat masks pressing on their eyes.
You sleep in a perfectly dark room and never travel - the cheaper Manta Original ($25) does the job.
