After reading all the reviews, I was quite skeptical. To me it is of course important that I smell not even a little bit of sweat, otherwise you go immediately into the shower. And normally I use a deodorant after showering and then I spray nor with Sprühdeo about it. But I would now like to do without aluminum and fragrances for breastfeeding, I had nothing else left to test as this deodorant. And I have to say I'm really surprised. It has kept with me one day and one night. And it was a really warm day! It's no sweat antiperspirant you though (as with any other aluminum without also), but it did not smell.
The little white layer interferes directly after application not (even this one has indeed in which one or other Deo also).
