Well, I will tell you if mine works. I just set it up tonight at the head of a rubline in the shadow of some haybails beside a small stream. I do not plan to use it for a little while I wanted to give the deer a chance to get used to it and my scent to leave the area. I set it on the edge of the timber because its hard to get shooting lains in the woods that I hunt. Ill let you know if it works.
