I tried the Trophy Rock for the first time last year. The deer did seem to like it and it lasted quite a while. I mainly use a product called lucky buck. It comes in a white bucket and looks like a fine red sand. I have been using it for about five years now and I'm not sure what's all in it but the deer go crazy over it. They will dig in the ground long after the product is no longer visible on the ground. Almost all the pics I post were taken over Lucky Buck.
