I am the type of person who perspires a lot, and by a lot, I mean a whole lot. I tried every type of deodorant, even the clinical ones that cost way too much for a deodorant stick. Someone finally told me about Lady Speed Stick 24/7. This was 7 years ago, and from that day until today, I have been using it and will not buy any other brand of deodorant. I use both the solid stick and the gel and they are both working great for me. Not only do they work perfectly and I do not perspire as long as I am wearing them, but they also smell great. My shirts are no longer stained with sweat stains, nor do I smell bad from sweating. Lady Speed Stick has not only protected me from sweating and smelling badly, but also protected my shirts and tops from the nasty stains left behind from sweating. I love using both the solid and gel, and will never use any other deodorant again. This one is working perfectly for me.
