Same here. I've tried it when I didn't see anything with no luck. That may be because they weren't near by. This is my first year trying it and When I see them I have rattled and grunted a couple within 40 yards that I know of but theres been a couple more that I'm not sure that they would've came my way without it. I still haven't seen them charging in like they do on tv but I think that it works with some. I've also had them to just keep going like nothing ever happend.
