I got some this year, no results so far, nothing like the videos show. I'm using it to hopefully calm any deer down wind.
Also have some but haven't used it yet. It smells like what I would imagine a barn full of deer and deer urine and poop would smell like.
I also bought it because of the lengthy thread that Schuls mentioned earlier. I've used it on probably 7 or 8 hunts but I cannot say whether or not it really works
