I agree. I tried one a few years back and had a doe coming crashing through the woods to within 5 yards. I only blew on the thing for 2 minutes and she was there. To tell you the truth it's the first time I saw something happen on a hunting video that worked the same way in real life. I couldn't beleive it. Then again, as stated earlier, it was pre-season and by the time our season opens it doesn't work as well.
