I have tried it a few times myself. It didn't produce anything for me. If I remember and don't quote me it kept falling of. Then it turned into mush because i left it in the car. All I can say is maybe try a bag see what happens but dont be dissapointed.
A loaf of bread and a bottle of vanilla or Superior Vanilla-Butter-Nut cake flavoring will be cheaper and work a lot better. I go to a place full of carp that feed on the surface and i fish another place with visibility beyond 12 feet. The carp never give the Power Bait a second look. Sure it may catch one eventually but bread is a gurantee in most cases. Gosh i want to go fishing now. Maybe tommorow.
My dad caught a nice carp on it just the one time,out of a whole bag.i had the same luck with the catfish bait i caught one channel cat,it was a nice one about 15 pounds but thats the only one out of the whole bag.I say keep your money.
