I've used a crystal deodorant for about 10 years and totally love it! In the beginning I had to get used to my underarms being WET and air drying after I put it on, but haven't given that little snag a second thought almost from the beginning. I put it on directly out of the shower before I dry myself. I love it! It isn't cheap, but it lasts forever like advertised - unless you drop it on the bathroom floor! I have a friend who swears by it for her feet. It is important to understand that it isn't an antiperspirant. Also, I've never had any trouble with staining on my clothes, not is it visible on my skin. Funny - I just remembered that years ago I would rub the crystal on my forehead and chin when they felt oily. Worked great! Haven't done that for years - maybe it cured me!
I'd suggest giving it a try if you haven't. I'm glad I did!!!
