I never thought I would be this excited about finding a deodorant that works! I have a stronger BO smell than most people and have spent 16 years looking for a deodorant that was aluminum free, natural, wouldn't harm my immune system and was safe to use. I've tried multiple natural brands, including making my own, with no luck. Every time I used them it was like I hadn't applied anything. After hearing about Pong and using it for the last few weeks, I am hooked! Best natural deodorant out there on the market by a long shot and I found that one application can last up to 36 hours plus. Thank you No Pong!
