Does Guanfudun support a 7-day no-reason return or exchange policy for brand-new unopened items? What is the return and exchange policy?

A: Woowhead Guanfudun supports 7-day no-reason return and exchange. Specific policies: ① 7-day no-reason return and exchange: Brand new unopened goods can be returned or exchanged without reason within 7 days from receipt (without affecting secondary sales); ② Quality issue return and exchange: If the product has quality issues (such as broken diaphragms, missing accessories, damaged dust collection bins, etc.), please contact customer service for confirmation before returning or exchanging. The shipping cost will be borne by the brand. ③ Failed film application: If the film application fails due to product quality issues (such as defects in the film itself or damage to the dust removal chamber), contact customer service for replacement or exchange. If the damage is caused by personal operational errors (such as dust ingress or misalignment), it does not fall under quality issues. It is recommended to use two spare pieces. ④ Dedicated customer service: From placing an order to getting used to it, a dedicated customer service response will be provided. If you have any questions, please contact the official customer service (official email: wow@woowhead.com, or customer service of each platform store). When returning or exchanging, ensure that the packaging is intact and all accessories are complete. Unopened films do not affect secondary sales. Note: ① Once the film has been opened and laminated, it is not eligible for return or exchange unless there is a quality issue (as it cannot be resold after being laminated). ② If any quality issues are found with the film after application (such as scratches, bubbles, or optical defects on the film itself), take photos as evidence and contact customer service. Once it is confirmed to be a quality problem, it can be dealt with. ③ The return and exchange policies of various e-commerce platforms (such as JD.com, Taobao, Douyin, etc.) may vary slightly. Please refer to the platform rules and store descriptions for details. Guanfudun costs 129 yuan for a 1-piece package and 159 yuan for a 2-piece package. It is recommended to purchase the 2-piece package to reduce the risk of failed film application.
