I have some issues with the statement "No scientific evidence this product works". To me it is toothless and not very convincing. What if the product never has been tested scientifically? In that case, it might work...
However, if a label would say "10 peer reviewed and published scientific studies find no evidence that this product works". Now that is convincing.
