I hate the stuff. For every time it works it screws me up 10 times. I was in northern Wisconsin way back on public chunck of land Saturday. I see this deer so I grunted. Half hour later it comes grazing. An old doe. 5 yrs for sure. It didn't have a care in the world till it got down wind of my doe in heat bottle. From then on it was stomping feet, quick head turns, and looking around all nervous. By the time I pulled back my bow it takes off snorting. I don't know if I would have gotten the deer but that stupid doe in heat bottle put the hurt on me. Ironically if it happened to be a buck when I grunted and it came in I would have thought it worked. I won't use it at all anymore. Wash your hair, arm pits and butt and you will be better served.
