I have used it many times. I’ve witnessed deer cross my entry path to my stand and not even notice, even though I had sprayed Nose Jammer on my boots. I also have had deer come in downwind and not spook. I have a video of a small buck that came in downwind and smelled the Nose Jammer, but it didn’t even phase him. He looked up at me in the tree stand and then proceeded to walk right underneath me, like I wasn’t even there.
