Redot S review
The cheapest credible red light device in the whole catalogue. Its higher surface number than the bigger Redot models reflects a smaller area sharing the output, not better engineering.
DISCLOSURE — we earn commission on purchases made through our links, at no extra cost to you. Rankings come from specifications and measurements, never from commission rates.
What we like
- Highest surface irradiance in the Redot line at the lowest price
- Long enough at 48.8 in to wrap most waists comfortably
- Same transparent measurement disclosure as the larger Redot models
What to know
- Only 5 in tall, so it treats a narrow band at a time
- Mains powered rather than battery, unlike the Hooga belt at a similar price
- 510(k) exempt, not cleared
