Warranty Policy

We offer a comprehensive two-year warranty to ensure you enjoy worry-free protection during use. The warranty period begins on the actual date you receive the product, covering all possible quality issues to ensure that your interests are fully protected.


During the warranty period, we promise to repair or replace products with quality issues for free, including but not limited to firmware upgrades, sending replacement parts, factory repairs and exchanges, to ensure your experience is optimal. However, our warranty service has some limitations. Specifically:


(1) Accidental damage caused by improper handling, such as dropping or collisions, is not covered by warranty;

(2) Damage resulting from misuse, and not following the product manual or user guides, is not covered by warranty;

(3) Damage resulting from unauthorized disassembly, third-party repairs, modifications, firmware flashing, etc., without written approval from Proxisky’s official after-sales, is not covered by warranty;

(4) Damage resulting from operation in unsuitable environments, such as water immersion or rain exposure, is not covered by warranty;

(5) Damage resulting from irresistible external forces, such as earthquakes, is not covered by warranty;

(6) Products without purchase records from official Proxisky website or authorized dealers are not covered by warranty.


For products beyond the two-year warranty period, we can offer paid repair services. Please contact your seller directly if your products are not ordered and purchased from our official website.


For product quality issues, we provide warranty service for products within the warranty period. If you encounter problems during use and need warranty service, please contact us.
