All products sold by CMC carry the manufacturer's limited warranty. All products sold by CMC are guaranteed to be free of manufacturer's defects for the term of the warranty dated starting on the date of purchase. All products are automatically registered for warranty coverage at the time of sale - see your user account on this website for a dated copy of your sales receipt.

Warranties provided by CMC or our manufacturer are not transferable. Original customers pay the costs of returning their products under warranty, and CMC covers freight back to the customer.


Like-new products returned for credit within thirty days of purchase are refundable in full except for customer's original, paid shipping fees. Sale/special, group-buy, bundled, coupon coded, B-stock, or close-out sales are final, but if we make an exception and authorize a return, will be subject to a 15% restocking fee. Return freight costs are prepaid by customer.

To receive credit, product authorized for return must be packed in the original packaging and must be in like-new condition, including all cables, accessories, and packaging inserts. Authorized returning items require a return authorization and must be shipped prepaid to the address we indicate. Items returned to our A-stock warehouse cannot be accepted and will be refused. Please allow approximately 5 business days after our receipt of the returned product and our verification that all requirements have been met for the refund. Refunds will be credited to Customer's original payment method.
