I love the gun because it doesn't waste bait like the other devises that push the bait out of the bait tubes. The only problem I am having is trying to get replacement tips. The tips are easy to break or bend and I would like to purchase a dozen of the #15 (large) metal tips. I have not figured out how to has the plastic tips that were included with the gun. We have 4 guns and none of them came with any instructions or diagrams to show how to maintain them.
