I have used it and had some succcess with it. It took a couple of weeks for the deer to really use it, but the does came into it and a buck decided to throw down 7 scrapes on that ridge. I think that it's something that will work much better in hot weather, because it's just flavored salt & sodium. I would much rather feed the deer Tecamate Horns a plenty during the off season rather than salt. But I did put out some buck jam a coule of weeks and I haven't been back to check on it yet.
