I have just ordered a deodorant stone & so far, it is working BRILLIANTLY! You rub it onto damp skin after washing & it's incredible - I have been finding that even 15 minutes after a shower, I can smell my underarms, but now I can go all day with not a single whiff! I thought I might just be going through a 'less smelly' phase, so after a few days, I switched back to my usual roll-on and the smell came straight back!
