Being new to bowhunting I'm willing to give anything a try, so I did. The 'smell' lasted all day while I was in my stand. It turns to a brown color after you spay it. I had one buck show up the third time I used it. Didn't get an arrow off. I think he winded me and left after getting to about 40 yards. The only complant I have is that the can I got doesn't 'shoot' the 'web' like in the picture. I don't know if it is under pressurized or what.
