*Our products have an IP67 rating, achieved by testing in distilled water under laboratory conditions. Please note that this rating does not imply suitability for continuous underwater use as it may result in damage. Additionally, the connectors on the product are not waterproof and must be kept dry to ensure proper functionality and safety. . The warranty does not cover malfunction or damage arising from the use of the products in activities where frequent or extended submersion in water is expected, such as riding in streams, rivers, or flooded areas. Over time, seals and components may degrade, reducing the water-resistant effectiveness of the product. Damage resulting from this natural wear and tear is not covered by the 2-year warranty.
