No crystals not help me, I decided to try something different. This deodorant is enough volume (twice our Reksony etc.) When applying the bluff there is the smell, I recalled something old-fashioned perfume :) over time smell a little weathered, but still there. 5-star rating, because coped with its task - no smell of sweat (although there is little humidity) + leaves no residue on clothes. I think that will suit and the man and woman.
