Review (4/5): works for those who break a sweat with little effort
My stepson can break into a sweat with little effort.
Also due to allergies many "high powered" anti-antiperspirants (ie those that cover up the smell of sweat with heavy scents) don't work.
This product while having some scent is not overpowering. And while it does not stop his sweat all together (he can be a sweat machine) it does notably decrease it during hot days and very active days.
