The ONLY aluminium free product that actually works. I started using NO Pong upon recommendation from two different friends. I had been hating living in the humidity of Brisbane, all my corporate uniform clothing contained some, if not all, synthetic materials, and I was sick and tired of sweating through my clothing and stinking all day from within half an hour of leaving home. Initially I tried original No Pong, but developed an itchy rash, however the awesome staff at No Pong offered to exchange it for the "no bi-carb" option to see if it made a difference - and it absolutely did in my case. I have been using it exclusively for at least the past five or six years and will continue using it forever. My absolute favourite is the bi-carb free Spicy Chai. It's all I need!
