I use them the same as the other do in this thread, and find them to work great. i use them in another way and found this to work great. I normally buy about 3 to 4 packs when i can find them in the stores. When I wash my hunting clothes in the scent free detergent, I dry my clothes in the dryer with one or two wafers instead of dryer sheets. I have found that this impregnates the clothes with the fresh earth smell. The wafers i use solely for the dryer normally only last about two to three in the dryer then loose their strength. Just thought I would throw this option out there. It works awesome for me.
