Absolutely LOVE No Pong. Rarely are things life changing and I'm not being hyperbolic but this literally changed my life. I had a change in body odor after getting laser hair removal and nothing worked. Not extra strength anti-persperant/deodorant, not men's deodorant, at home remedies, nothing. Also, antiperspirants have aluminum that can increase risk of various medical condition - this does not. I gave No Pong a chance 4 years ago and never turned back. If I'm not out in the sun all day, not doing strenuous exercise, then it lasts way longer than 8 hours. Often I'm still smelling fresh the next day! The only downside side is that it temporarily stains whites when wearing them. The pit area turns very,very yellow when I sweat - I rarely wear white anymore. It washes off and is not permanent on clothing. I could not live without No Pong. So grateful for it.
