This deodorant I have not purchased through Amazon. And I can only say one thing, that my opinion is not bought, as some suspects here. I am a woman, am 30 years old and I sweat very heavily, whether summer or winter. And this is the only thing that keeps me Deo "stink" by and it actually lasts all day. The only thing that bothers the white film is produced when applying and then crumbles to the clothes, but this protection is to me the all value. I really have tried every deodorant of natural cosmetics, spent a lot a lot of money and now thank the people who created this deodorant. I think it's expensive, and it wears out quickly, but as long as it is in the range I will buy more of my life, as I have said as yet found no more effective deodorant !!!!!!!!!!!!!!!
