I own one and like it... the deer where i hunt in alabama dont seem to respond much to calling anyways but its nice to have in the bag just in case... I do also hunt in Miss. and called i two bucks with it last year. Neither of these were mature deer, both year and a half year olds... I dont think that the age of deer decides whether or not he will be aggresive or not. Deer are just like people, they all have their own personalities.
