Every manufacturer offers a “Lifetime Warranty”, but this applies only to the original owner. In almost every instance, the manufacturer charges a handling fee, and you also need to know that it will cost you a minimum of $10-15 to send the rod in to the manufacturer, or have your local shop ship the rod, in addition to that handling fee. In most instances your rod will be repaired, not replaced but this varies from one manufacturer to another.
