Full disclosure: I am not a gel deodorant fan, but I really like this one ;). I can definitely tell a big difference in this compared to my Secret Outlast soft solid that I have used for 15 years because I can go 2 days and not wear my Secret and never smell or sweat. With this one, I sweat a bit and after 12 hours, I will smell a bit, but that is actually a GOOD thing! That means there aren't harmful chemicals clogging your pores and leaching into your body, which can lead to things like cancer.
Although I prefer the coverage of my Secret better, I will definitely sleep better at night knowing I am not pumping those chemicals into my body with this one! Definitely a worthwhile investment!
