Finally found someone who mentioned LightWorks, and subsequently, SOTA. Pretty impressive. I love the phone cord connection - inexpensive and any length I want. Also, that it doesn't run on batteries that will constantly need to be replaced or recharged. And the addition of the frequencies is brilliant. From what I've seen, this is the most comprehensive and least expensive way to deliver the healthy benefits of light. Great price, well thought out design, easy, versatile implementation.

I have bought five LightWorks Infrared instruments. We gave the SOTA LightWorks to all of our children. Most of them use it regularly. I find the LightWorks is most helpful. I have many, many examples of its use. Thanks for making them.

I have now used the LightWorks daily, usually for an hour, for about 6 weeks. I am most pleased with the results. I discovered the Near Infrared side worked best on my knee. I am very satisfied with your product.
