I've tried many many many deodorants and antiperspirants over the years and finding one that is both alcohol and aluminum free that actually works is difficult. I thought I found one last year and it seemed to work, however it left an oily residue on all my dress shirts that I couldn't get out. It also left white marks on all my clothes.
Alas, I tried this one from Malin+Goetz and it is fantastic. It keeps me dry ALL day. It smells really fresh. And it leaves on marks or residue on my clothes. After going through a full container, I just purchased 5 more. I'm now committed and truly happy.
