I have used this for the past couple of years. I spray it on my lower pant legs and boots when heading back to my stand. Once on stand I open the bottle (unscrew the sprayer top) and just leave it open on the back of my stand. Yesterday morning I had two does come in and move down wind from me. It was obvious when they caught wind of the scent. They stood around for almost 1/2 hour noses in the air and they kept look intently in my direction (but not up at me). They walked around the tree several times trying to figure out where the deer scent was coming from. Eventually they moved off.
I am a firm believer in this stuff.
