I've used it twice. The first time I used it I didn't have any luck b/c the club beside us let their dogs out and started running deer. The past Saturday, my dad and I both put some out and he heard a deer blow at him. I don't know if it was b/c we were hunting on the ground and the deer may have smelled him. We were using the "Doe P" one. Probably going to try the doe in estrous this weekend.
