I bought a smaller version of their red light therapy just to see if it really works. I was surprised by how much it helped with the tension in my neck and back. I bought this larger one to use on my horse! I think it is helping (he really hasn't said!!).
I have had laser therapy previously and am happy to have the light therapy at arms length instead of having to make an appointment and go somewhere for nothing more than a 10 minute treatment. I use my belt at least 2x a day and on different areas. The first improvement would be to make the cord on the corded version much shorter. Pic attached is my contraption for keeping the cord under control. Completely unnecessary for it to be that long. The other improvement is for the USB connector to not heat up during treatment. It has almost burned my skin so I have to pad the area with a thick cloth. Both my fixes work but I’m sure you could do better. That said, however, I really like the belt and am happy with my decision to buy it.
