Put out some $10 a bottle doe in estrous and had several crusing bucks pass it without so much as any reaction. The first buck passed less than 10 feet from it a half hour after it was out, no reaction what so ever. Do I have to step up to the $30 a bottle stuff or just change brands? I know the stuff won't bring them from 10 miles away but when I need them to come my way that last 10 yards, I'd really like something that works.
