I use them a lot and different types of scents--if nothing else they help hide the scent of handling plastics by us. Cant hurt right. I have even heard of using wd-40 as a attractant. I never have but know others that have. For some reason i have better luck with them in the fall and winter. I dont know if fish smell better in cool/cold water or what. Theres my 2 cents. Later jc
