They should last you a lot longer then 5-7 years...
Only rod I've ever broken legitimately was a St.Croix Avid that snapped a few inches above the handle when I set the hook on a big pike. Other then that, nothing.. I've got rigger rods from the early 80's that still get use anytime I'm downrigging.. Love those things! Guides could use a re-wrap but other then that they are mint,.
