Broken an Abu, BPS, Carrot, Fenwick... All replaced from the companies and they were all great to deal with. Shimano has a great warranty over the counter but I don't think I have known a single person that has owned a rod without it snapping.... Most have many many times. .. They need that warranty to keep the customers happy.
Kistler was by far the worst experience ever. Always got the run around and they wouldn't help out at all. I would never buy another energy of their rods ever.
