I bought Fussy on a "don't try, won't know basis", as I've been using a commercial brand of deodorant for ever, quite unhappily. The promise of an all natural, aluminium & paraben-free and 100% vegan deodorant was rather promising, but it got me somewhat (paradoxically?) perplexed as to its efficiency. Was I wrong! Not only does Fussy works, it exceeded my expectations. I have been using it daily for about two weeks, and it hasn't failed on me once. No traces on my clothes, very comfortable (no sensation in the armpits), great performances throughout the day... It's exactly what one would hope from a deodorant. I'm happy to not have to worry about my armpits again :)
