This is the only natural deodorant that works (for me). Yes, I tried the rock crystal deodorant 15 years ago and it didn't last through the subway ride to work, so I gave up. Last year, after hearing amazing things about Schmidt's, I decided to give natural deodorant another try. I am so glad I did. The scent isn't overpowering and the formula doesn't irritate my skin, which other natural brands are known to do. This formula lasts all day and even keeps scent at bay during my nightly hot yoga class. If that's not a ringing endorsement, I am not sure what else to say!
