One of the most decisive factors for DUAN’s success is the efficiency and availability of its support area, particularities that arise directly from the conviction that we are responsible for the quality of what we offer to the market.

Therefore, as manufacturers, we offer after-sales services for an indefinite period, and a oneyear factory warranty 100% free of charge (shipping not included) except in cases of misuse of the product, as set in the warranty manual.
