I for one purchased the Buck Growl From M.A.D Calls. The footage that I seen from a bowhunter in Illinois on a buck making this sound after the hunter shot a doe was unreal. After the buck made this vocalization it brung in five other bucks. On the DVD that comes with the call Mark Drury calls in two nice bucks using this call. I feel if the conditons are right this call will work and as they say this call should be used in the rut phase. This call also can be used as a grunt call as well. The little bit I have played with it I feel it has a good sound to it whether it be the Growl or the Grunt. I never had any luck with the Primos can for deer, but for fall turkey that is another story.
