My buddy and I used it last year, but got it put out kind of late but they attacked it pretty much instantly. In fact during turkey season this year they seemed to have seriously increased activity around them. A great recipe and in fact there were some pretty nice buck around last year, Expecting to see better ones this year, we are pretty sure 3 8pts survived the season and the winter so we' ll see how big they get and if the minerals helped at all.
