This Roll-on comes in a small glass bottle, the contents of which is applied using a rotating plastic ball evenly, thereby sparing the armpits. The application is so simple and accurate than the Sprühvariante.
Whether the specified protection for 48 hours, really holds, I can not say. I would then also has 24 hour totally rich.
After the application is needed - at least for me - a few minutes until it is completely retracted and dry. In retrospect, accompanied us a fresh scent that sometimes keeps even over several hours. After application, it was also a little fresher than usual under the armpits.
With the same effort and conditions it seemed to me that as if the effect of these roll-ons is better. I had the feeling of having less sweating as if I take normal spray deodorants. Maybe it's the fact that the plastic ball soothes the glands under the armpits? I do not know unfortunately.
Conclusion: Deo Roll-Ons have shown a better effect for me as deodorants that you spray. Maybe it is just me, but I could well imagine that I still also use roll-ons and thus use the spray version.
