I'm really happy that I found No Pong - it is the best of all the natural deodorants I've tried! It really does work the longest, and I put my deodorants to the test through night sweats and workouts and yard work. I use the Original - I do experience some irritation, and have been meaning to try the no carb variety to see if it is better. Cons: the container is impossible to open, especially when you have wet hands post-shower. I have to leave it open or pry it apart (and send it flying across the room). I just ordered a makeup sponge to try to use as an applicator, as I don't like using my fingers to apply,
