Review (5/5): Works great!
Normally I just grab a vegetarian and rub them in my armpits, but this works even better. I have always had issues with aluminum based antiperspirants, and this lasts most of the day and smells like fresh cut 2x4's.. I keep looking around for a construction site, but it's just my armpits. Seriously. Take a hatchet to a pine tree - this is what it smells like.
It's kind of mushy, so you have to put it on sparingly or it just clumps up in a ball. I screwed it up too high the first time and smeared like a tablespoon in my armpit. uhg. But if you just screw it up a little bit each time (1mm +- 0.75mm) it works good.
Overall: A real win, the best non-aluminum anti-perspirant I've tried. It's too mushy but you can deal with it. Doesn't seem to stain my clothes.
