After reading great reviews for this product and not looking at the price, I decided to buy and try it. Definitely decreased my underarm perspiration. I was in the middle of moving to a new home during CA summer and my plain white shirt had visible sweat under my pits. Embarrassing. After receiving this product, I took a shower before bed and applied this. The next morning, working hard to organize my things to my new place, I did perspire..... but very minimal! It is also easy to wash off. It is not sticky at all. I use about 2 pea sizes for application. It doesn't leave a rough residue unlike common deodorant. Though it doesn't completely stop me from perspiring I'm glad that I can now wear colored tops during summer without my arms being stuck on my sides!
