To get to the point that there are only 3 stars because the deodorant works without aluminum salts. The Deowirkung is long lasting and good, but over fragrance and compatibility you need to talk. We come to the fragrance. The term "Ocean" does not fit here really - unless following the sinking of a chemical tanker. The scent of this deodorant is rather artificial and intrusive (though fresh) wants, say, one smells in even after 24 hours - like it or not. Since you would rather skip the 48h effectiveness ... Now for compatibility. This deodorant is in years, one where I felt a skin irritation under the armpit, to a slight burning sensation. That is (at least for me) still acceptable, but I think for many a quite a knock-out criterion. That the skin tolerance "dermatologically tested" is, though it is, we come before something surprising; but you also do not know what has been tested since.
The bottom line is I would not buy this deodorant again, though it does its job quite decent, what fragrance and skin tolerance, I would regard but resort to other products.
