Cons: can't think of any
I have tried just about every natural deodorant and I have never found one that even comes close to this one. It really does completely eliminate odor right away, and the more you use it, the less you sweat, and the less you need. The company says that it get's magnesium and potassium into your body which are really important minerals. I'm so glad I found this deodorant. It only comes in unscented so far but they're facebook said they would be coming out with scented ones which I'm excited about.
