DGYAO
Cordless Rechargeable Red Light Therapy Waist Belt review
A contact belt quoted at 1 inch rather than at the surface, which makes its 80 mW/cm2 slightly more conservative than it first appears. Check the exact model number before buying, because DGYAO's listings vary considerably.

What we like
- States a measurement distance of 1 in, which most belt brands omit entirely
- Detachable 4000 mAh battery gives around three hours, longer than most cordless belts
- Attachments for knee, foot, hand and shoulder run off the same controller
What to know
- 144 LEDs is the lowest count of any belt here, roughly a third of the Hooga
- DGYAO sells a confusing spread of near-identical models across Amazon with different LED counts and wavelengths, some using 880nm
- No FDA status published
