Important After-Sales Notice
Please be advised that any claims regarding product defects or malfunctions must be supported by clear video or photographic evidence explicitly demonstrating the specific issue during installation or operation.
Without visual proof, we will be unable to process replacement, return, or warranty requests. This measure enables our technical team to efficiently verify issues, preventing unnecessary returns or misunderstandings.
Installation is not included. We strongly recommend professional installation. For all verified quality issues, we will provide comprehensive after-sales support.
