I've had some success with it. I rattled in a 115-120" 9 pointer this season....to about 40 yards. I wasn't going to shoot, but wanted him to come closer. I grunted and nothing. I then just tried the 3 quick "ffft ffft ffft" of the snort / wheeze and he came ripping / tearing everything in his path straight to the base of my tree....probably the coolest thing I've ever seen a buck do. I've never heard a buck do the wheeze portion of the snort / wheeze so I don't do it either...and it has worked for me.
