Quantum products that fail at any time will be replaced under warranty if it is determined that the failure was due to a defect in workmanship or material. This warranty only applies to the original customer and is non-transferable. Improper use or installation of the product voids this warranty, and Quantum is not responsible for incidental costs resulting from failure of the product. In the unlikely event that you should need to request a warranty, please contact us at email@example.com with your order information and a detailed description of the problem.
