Yep, they work. They wont make more fish taste your bait, but they will make a fish hold on longer. Instead of using super concentrated mixes, I get an old washed out (with baking soda) baby wipes container, and cut out the grooves from the "pop top". I add a bottle of my favorite attractant, add a small bottle of anise oil, about 8 tablespoons of garlic salt, and mix. You can still close the top, and just pop it open and dip your bait in the hole as needed. No more spraying everywhere all over the boat.
