I've tried a few different oil control products, and the one thing I've noticed about most of them is that they stop working within about an hour, if that.
Not so with this.
I was pleasantly surprised that this actually keeps working for a good while.. It also has a decent citrus-y fragrance, unlike some of the other ones I've used that smell like chalk. Want to get a few extra of these to use when I travel and keep one in the gym bag for sure.
