I have tried most natural deodorants, and tend to break out from certain ingredients, so have had trouble finding a non-irritating, effective deodorant. This is IT. It works better than my Lavanila (which was my previous favorite), and better than the sadly-discontinued Body Shop roll-on. No rash, no soreness, no discoloration, and NO SMELL after a day wearing a synthetic base layer and a sweater (which is ususlly when my natural deos fail -- not on warm summer days where my pits can breathe, but when everything is trapped in). Takes a few minutes to dry/soak in, but I can live with that, Also, has not stained my clothing (Primal Pit Paste works great for smells, but oil stains my bras...ewww).This doesn't keep me 100% from smelling at the gym (only Primal Pit Paste has worked that completely on smells...but again...terrible staining of clothing), but I can live with that. I shower after my workout, and it does keep the smell way, way down, so that's enough for me.One more tip that's going to sound preachy, but is just something I've noticed that you can take or leave: diet really, really affects how much your sweat smells. I go through periods of eating like a clean, nearly-vegan, no-processed-food champ and those of...really not doing that...and it's amazing how much it affects my smell level. I'm between extremes now, and this deo is working great for me.
