This deo stick has a VERY strong smell. It's not unpleasant but does remind me a little bit of insect repellant. I have only used this twice as I prefer the scent of "no pong", it's possibly more a masculine scent. However the application of this is super easy, which is a huge plus. Seems to work very well, although I am yet to test this after exercise. I have sensitive armpits and usually use the bicarb free versions of natural deos, so far I haven't experienced any discomfort with this one.
