I have recently switched to using No Pong, and converted swiftly after the first day of use! No Pong works better than any spray or roll-on deodorant/anti-perspirant I've ever used! I had to find an 'alternatively packaged' deodorant, as my weak hands were no longer able to use a roll-on. I'd seen the ads for No Pong and knew it came in a small tin, reasoning that I could use a knife to open the tin if my hands couldn't do it. I am very happy that so far, my hands HAVE been able to open the tin. And absolutely amazed at just how well No Pong keeps my underarms odour-free! It also readily washes off in the shower, much easier to wash off than the previous roll-on. Winner winner!
