I am obsessed with finding the perfect deoderant. Knowing of course that nothing's perfect, I still would like to find a deoderant/anti-perspirant that works really well. I am tired of having stinky pitters. Arm & Hammer Ultramax works REALLY well, but after about a week, it loses it's effectiveness. I have decided your pitters build up an immunity to it, so you have to switch them around weekly. Problem is, I can't find another one that works well. I have even tried a man's deoderant recently...that didn't work very well.
