I can say, without hyperbole, that this stuff is life changing. Now, it isn’t earth shattering - it doesn’t keep me completely dry all the time regardless of temperature or situation. It DOES, however, keep me MOSTLY dry MOST of the time. This means I don’t have the worry about wearing the wrong kind of fabric of color for fear of epic pit stains. It also means I can wear deodorant rather than antiperspirant which is going to mean that items of clothing such as T-shirts and dresses will last much longer as I will no longer have to deal with the gross build up of antiperspirant that is inevitable with anything worn with any regularity. Nothing has ever worked this well - not OTC antiperspirants, prescribed antiperspirants, or Botox. If you’re unsure, do yourself a favor and at least buy one box and give it a try. I’m confident you won’t regret it - like, wear-a-heather-gray-cotton-T-shirt-at-a-summer-afternoon-cookout-without-shade kinda confident. ;)
