No Pong - no bicarb - is the very best deodorant I have ever used, and I'm in my seventies. I always sweated in summer and thought I was also smelly. I tried the No Pong original and was allergic to the ingredients, coming out in an armpit rash. I contacted the company and a free no bicarb was sent to me. Love it, love it, I have now bought 4 of these online and am telling everyone I know who has suffered from sweating in humid conditions (I live on the Sunshine Coast) to experience this product. I also have no perspiration odour at the end of the day, and my clothes don't smell. This is an excellent product........CP Sunshine Coast
