Ive been using it a fair amount the last two seasons with pretty good luck. Its just like any other call, when used at the right time to the right deer it will work. Mainly its used during the rut when bucks testosterone levels are high. When you snort wheeze at a buck its pretty much saying "IM GONNA WHIP YOUR A**" Deer are just like people some might come over and say go ahead and try it, and others may avoid the situation either because they are smart and can find hot does other places or they are scared.
