I've bought several of them, the whole family uses them, from my brother-in-law with a back injury from work to my grandmother. We've nicknamed him "Doctor Red." A good alternative to doli.
Received today, feels good on the skin. Warms well, l4 was too hot, l3 is perfect. Comparing to a similar device for $300 (6 times more expensive than this one) that my friend has, this one is a bit simpler, instructions are not clear, the belt material is not as smooth, but i believe it does the job well and the red light works. As long as you believe in it's curing power, you will benefit from using it.
Ok
The belt is very wide and not rigid at all, which is a very good point. I am delighted with my purchase and find that it brings me a lot of warmth and well-being for my back. Thank you.
Thanks
