It works pretty well. Not 100% effective but much better than not using it at all. Also, the top has on more than one occasion come off in burst of powder into the air all over the place. Not a big deal but one time I had already put on a black shirt when I realized I forgot this stuff, so I pull off the top not thinking and POUF, you get the idea. Aside from that minor issue in design, this is a pretty solid product all in all.
