here is my experience with them. I have tried them for years and have never had one come in while using it. It may be because the buck doe ratio is way out of whack here, but im working on thatI have tried it (tickling in early season) tried it pre rut, rut, post rut with nada. I think alot has to do with the area your hunting and the buck to doe ratio balance. I have tried it on bucks sighted at a distance only to just have them look briefly and not be interested. but the one thing i have noticed it does not scare them. wast of money? probably not, but it may work great for you and i hope it does. good luck!!
