Query: Miracle Worker

This product is simply amazing. I thought this would never work for me, being that I have tried everything on the market including prescriptions. Nevertheless, I've been using this for about two weeks and I'm dry as ever. Usually, I would have a tropical rainforest under my arms. If you tend to sweat a lot trust me this will work for you. Like I said I've tried everything and this is the only thing that has kept me dry and I still can't believe it!
