Amazing!
Working in a warehouse, I NEED a strong deodorant (even during winter months you drip sweat). This stuff works wonders! Prior to this, I was using their ultraclear kind since I wear a lot of black, but it wasn't cutting it in the work setting. Sadly, I have noticed discoloration in the pits of my work shirts since I've started using this. Something to keep in mind if you wear expensive clothes. (I don't so it doesn't bother me too much).
