they are the best i every used on deer hunting. i had deer come in that i never did get a picture of on the camera and i shot a 10 point last year with it. and i wasn't out but about 1 1/2 hours and i had 5 bucks in to it and i just picked the one that was biggest and pulled the trigger. but when i went home and came back the next morring they was rubs and scrapes all over the place where i was hunting the day before. so i'm goin to use them again this year they seem to know what kind of scent you need to bring in that big buck
