Poor documentation but some good results..
This is a stout build. You won’t need any persuasion to wear the light blocking goggles and you will be able to feel the warmth. However I was at a loss because the booklet that came with it which I was sure would give me instructions and parameters for the protocols was a marketing brochure. I have no idea how far away my body should be, for how long. The remote doesn’t work so I have to peek through the edges of the goggles with one eye and carefully creep around to the back to power on/off. It has not helped my peripheral neuropathy in the month I’ve tried to use it. On the other hand, I have had continuing pain in my three year old knee replacements which is now gone, a real improvement. I have only used the Deep Tissue program, still leary about distance and duration. I wish there was a detailed, straightforward user’s manual in paper or online that wasn’t confusingly corrupted with marketing!
