Query: Does Not Work

I was excited to try this product; its reviews were terrific. I perspire very minimally without any antiperspirant, and not at all with typical drugstore antiperspirant. I tried thsi salt deoderant product for six days. Each day the product failed, I perspired, and so each day I applied more and more layers of the product. The additional layering made no difference. I wish I could recommend the product, but I cannot.
