I really like this product. It was easy to spray, and very effective - I didn't sweat at all when using it. It made me feel instantly fresh, and it has a light fragrance that doesn't overpower. I haven't noticed any white marks, which is great.
I have noticed that it does sting slightly if I use it too soon after I've removed armpit hair.
I found this was a good product but I couldn't find or tell any difference between it and a different kind of nivea deodorant. I wouldn't say its specific for stress related sweat either. It does smell clean and refreshing though which is good.
