I shot a buck in WV over a "Buckrut" flavored one back in 1999 or 2000, which is the only time I ever had a deer come running to scent wafer. I put that wafer up, climbed into my stand, and saw him coming fast and on a string before I even got my bow pulled up. he trotted right to the damn thing, put his nose up to it and I shot him bare fingered at 7 yards. I used them a few times in conjunction with rattling/calling with my decoy, too. pretty sure the deer that I could tell actually smelled them seldom paid them any more attention that just simple curiosity. waste of time and money, imo.
