When used correctly, Dopa can have a long-lasting effect. We have owned our band for over 5 years, and it is still in excellent condition. The band’s longevity is dependent upon the level of maintenance it gets. We provide a 1-year warranty as we are unable to take responsibility for any actions individuals may take with their sports equipment at home. Here is an article that provides guidance on the correct methods for storing and maintaining Dopa over a prolonged period. If your Dopa accumulates dirty marks, please remember that Dopa can be washed since it is water-resistant.
