Works and I see no reason for a devaluation.

Who Stinking with Deo fight (must) has anyway a stench problem.
This shoe deodorant does what it is supposed to do and glossed over reliably each specific shoe odor ;-)
The smell is bearable and not pushy.
In principle, a great thing. And for all that devalue the product here: Buy some times a second pair of shoes, so the first time, has air out ;-)
