The product must be returned to Vapor Trail, Inc. for technician inspection and must accompany a Return Authorization Number (RA#) that is provided by our Warranty Service Department. Vapor Trail, Inc. will not warranty any bowstring that may present a safety hazard. All RA#’s must be returned within 30 days. Any product returned without an RA# will NOT be subject to warranty repair, replacement, and/or a refund. Returns may be subject to a restocking fee at the discretion of our warranty department. Dissatisfaction with the purchaser's color selection or a combination of selected colors for bowstrings does not qualify as a manufacturer defect, therefore is not covered under warranty. Please call (763) 862-8870 to speak with a Customer Service Rep to receive a RA#.
