Has Mitchum changed it's formula? I've used their roll-on deoderant for years. It was a perfect product, no odor or wetness at all for up to 2-3 days. In the last 2 months, the last bottle I bought is thinner, less milky, and doesn't work. I am wet and have BO within 4 hours. What's up with that? Why on Earth would Mitchum change it's formula to something that doesn't work?
