The only way to be absolutely certain that you are purchasing genuine Cardas cables is to purchase new cables from an authorized Cardas dealer or distributor. New Cardas cables come in the correct packaging for the model (see our page on packaging), and come with a numbered Certificate of Authenticity.
As the manufacturer of course you expect us to encourage you to buy new cables. However, we are proud that our cables retain good re-sale value, and want to help second-hand buyers have a good experience.
So... Beware of counterfeits when considering the purchase of second-hand cables. We have come across a number of counterfeit Cardas cables. Some closely match the appearance of genuine cables, others are so poorly done that their print contains typos.
