I swear by the crystal deodorant, but it was completely ineffective on my son. This may be due biome differences between the young and middle aged.

EDIT: I use normal soap and shampoo.

I also use one of those and never smell at all, but I also wash with soap. Perhaps it's the crystal, not the lack of soap that does the trick?

I've used the crystal for about ten years. Stopped soap three years ago. My smell improved after stopping soap.
