We sincerely apologize for the inconvenience caused. Please note that all products are thoroughly tested before shipment to ensure they are in perfect condition. The E2 alarm you reported is most likely due to transportation damage, for which we already sent spare parts, a video guide, and even tried to call you, but we have not received any response. Regarding the “high amount of VOCs,” this is not part of our standard testing and we are not clear about the source of this information, so we kindly request more details in order to analyze it properly. We are committed to resolving this issue, but without your cooperation and feedback, it is difficult for us to move forward. We sincerely hope to hear from you soon so we can provide a proper solution.
