I used one of these at my local sauna. There are 4 panels.
I’d had a boil that would bit heal and i was on the brink of getting antibiotics. Had two sessions of red light therapy and the wound was gone.
This is a well built quality piece of equipment. It could do with a carrying handle on top and a nice box for storage purposes. And the instructions could be a bit clearer. For instance, I am treating my lower legs, so should I do 10 mins on the front and then 10 mins on the back?
Easy to assemble and very robust. Keeps the main unit secure and free from potential damage. I would highly recommend.
The battery life is too short, and the unit get's very hot at the end where the light is emitted from
