Thanks DVT, you beat me to the punch. I would like to see more companies do this. Or, make it optional. I'd be perfectly willing to buy a good rod, say a St Croix, without a lifetime replacement guarantee, if I could buy it for a lot less. Why should I have to pay for somebody else insurance?
I have never bought a rod with a manufacturing defect that caused it to break, and I've been fishing a long time. I have however, broken a lot of rods. Every one of them was my fault. I've stepped on them, slammed them in doors and tailgates, dropped one across a sharp edge, broke two when the braid was wrapped around the tip when I set the hook, etc. I did NOT send any of them in for a free replacement. All were my fault.
Why should a rod manufacturer have to pay for my stupidity? Even worse, why should I have to pay for yours?
Defects in workmanship are fairly easy to spot for the most part. You can spot them before purchasing. Some defects are not so easy to see. A poorly glued seat, or badly mixed epoxy are some problems that may take a while to show up. But they will show up quickly. A defective blank will break during the first few casts, and if not then, it will break on the first solid hookset.
I have seen a lot of rods with defects. Crooked guides, messy or cracked epoxy, dorked up reel seats, bad cork, mis-aligned components, warped blanks, you name it. I've never bought one. If you bought one like that, it's your fault for not inspecting it in the first place.
If a rod breaks after being used for a couple of years, then it is your fault. You did something wrong.
