Well it is one way to distribute deer piss. I have one. I didn't follow the directions, which say to press the tab in so that the can contiues to spay even after you set it down until it is empty. I simply used it to spray on the bottoms of my boots,more as a cover scent. I think it is probably the best container for keeping the piss fresh, since no air is introduced into the can, but I can't say whether it works or not. It is probably the most over used product on the shelves, which leads me to believe that the deer are probably learning to stay away from it. At least in my area of VA. Just about every store is sold out of them and at around $10 a pop, that's a pretty big investments to spray in the air.
