For many years, I take this roll-on deodorant and am since day enthusiastically. The distinctive smell is clearly perceivable, but not unpleasant. Once you put on a t-shirt, you can take the smell only was very weak. Whether it keeps really 24 hours, I can not say, but I did not get the roll-on deodorant to long to its limits. Everyone should nevertheless be clear that this is not a substitute for personal hygiene.
