It has worked well for me. This morning when i went to check my trail camera i spotted a doe standing over an old buck jam site from a month or longer ago. I went and checked it out and the doe had had made a dent in the ground where she was licking it. I have deer cane in front of my camera now and it works well too. I have found out that buck jam, deer cane etc. are all about the same and they all have the same ingredients as a mineral block. The thing that makes buck jam slightly different than the rest is that it smells.
