Near-infrared light waist belt, red light LED waist belt

Near-Infrared Light Waist Belt Red Light LED Waist Belt
Fatigue Recovery, Rehabilitation

Purchased on Amazon, but I'm selling it because I bought a larger size.
It has only been used 2-3 times and is in very clean condition. However, as it has been stored at home for a while, the outer box has some damage. Please consider this before purchasing.

Brand: Derlights
Size: 61*30CM

[Special Chips & Infrared Lamps] The near-infrared light and red light waist belt is an updated version with a 2-in-1 chip design. It includes 660nm red light chips and 850nm infrared light chips.
[Large Size & Versatile Application] The large size of 61x30CM provides a wide irradiation area. This near-infrared LED and red LED waist belt can be used for discomfort in various areas such as the waist, back, shoulders, neck, elbows, arms, thighs, and knees.
[Portable and Easy to Use] The material of the infrared light waist belt is soft and pleasant to the touch.
[Special Timer Design] Considering that the effectiveness of red light belts varies with different usage times when using near-infrared light and red light at home or elsewhere, we have designed a timer function. We recommend not exceeding a maximum usage time of 30 minutes.
Easy Operation: Simply connect the belt to the adapter and press the power button to use. The power button can be used to turn ON/OFF and adjust brightness (5 levels), and the M button can be used to switch modes (3 modes).
