Our obligation is limited to the repair or replacement, in our sole discretion, of a product that proves, by our sole examination, to be defective under normal use and service during the warranty period. If a product is no longer available, replacement may be made with a similar product of equal or greater value, in our sole discretion. We reserve the right to alternatively refund the money actually paid by you for the product, in our sole discretion. The warranty period is not extended if we repair or replace the product or issue a refund. We may change these terms in our sole discretion, but any changes will not be retroactive.
