I have used it a few times including this last weekend when I got my tom. I had set up a jake and a hen in the mating positionalong with another hen. Therwas gobbling and yelping every where so I yelped softly and used the Primos Gobbler Shaker 2 times only. I started with a wing just beforeI thought the birds would fly down than another jus after they flew down. I think the Shaker just helps make them feel safer and they gobbled at it. I always keep it with me hunting.
