I was so glad to be chosen to try this product. For work I have to wear a black or white shirt and every antiperspirant or deodorant I have used have left marks in the pits of the sleeves and it's very annoying. But not this one. Not only does it not mess up my shirts but it gives you oder and wetness protection for 48hrs. Waking up at 4am every morning I tend to forget and it's not a good feeling.
