i first started using them when i saw a doe coming through the woods with smoke coming out of her ass and some good bucks following here. Smoke coming from deer is very natural so i gave them a shot hahah j/k, seriously though i have used them with pretty good results, especially the rut rageous sticks during peak rut. also decent results with the curiousity sticks. Tinks makes a similar stick that works just as well.
