I do not know to whom he can and does not help to remove the smell of armpits, to me it was very helpful, I smelled like a horse: D at least 20 times pomoysya. This crystal works even when pomoesh evening, in the morning there is no smell. Today was sweating all day, heat 35, running before the day of birth to the market, the crystal passed the test at 100%, in the evening the smell of sweat is not at all. 5 (updated-10.02.2015) It turns out there really are people who it does not help, my mother is just not how it helps the smell.
