I bought the buck roar cuz I heard it doesnt make the ducky sound, and i only had one time that it may have worked. I had a nice 140ish buck run by me during rifle season and hit the roar and nothing, maybe he winded me or something but he didnt have his tail up so i dont know. But I do know that small 5 pointers dont like it. They took off after i tried to call in him in for fun.
