I've heard some pretty good things about the ones for deer. If a buck smells them they come in. A friend told me he actually had a buck try to hump the bucket that he was using with them. Make sure you follow the directions exactly. He tried it without following the directions and it didn't work. The big thing is the deer has to smell them. If the smoke is going straight up no deer is going to smell them. It might take the right wind conditions for them to work.
I'm going to give the moose sticks a shot this year.
Good luck!
