I use Tom's Natural deodorant because I don't want the aluminum, but I have to say that I don't think it (or any deodorant) works well. Antiperspirant is so much more effective. But, probably harmful, so I'm just going to have to live with reapplying deodorant twice a day unless someone invents something better. I've also tried the crystal thing in the purple container. Didn't work any better than Tom's, but is messier to apply.
