How is the after-sales service of Guanfudun? Can a damaged film be replaced?

A: After-sales policy of Woowhead Guanfudun: ① 7-day no-reason return and exchange: Brand new unopened goods enjoy 7-day no-reason return and exchange; ② Dedicated customer service: From placing an order to getting started, a dedicated customer service response will be provided. If you have any questions, please contact the customer service. ③ Film application issues: If it is a product quality problem (such as defects in the film itself or damage to the dust removal chamber), contact customer service for replacement or exchange. If the film is improperly applied by yourself (such as crooked application, dust ingress, or air bubbles), it is usually not a quality issue. However, you can contact customer service for consultation - some brands offer a discount on reissuance for users who fail to apply the film for the first time (please refer to the customer service's response for details). ④ Problems during use: Such as abnormal detachment of the oleophobic layer, non-human-induced rupture of the diaphragm, etc., can contact customer service for assessment. Suggestion: ① Read the instruction manual carefully before applying the film. Use the dust removal chamber and follow the steps. The success rate is very high. ② If it is not stuck properly the first time, do not repeatedly tear and stick it (as this will increase the probability of dust ingress and damage). Contact customer service for assistance. ③ Keep the purchase voucher and packaging for convenient after-sales service. As a new and emerging brand, Woowhead usually responds positively to after-sales service (the brand values its reputation). A 2-piece set priced at 159 yuan also allows you to practice with one piece and keep the other as a backup, reducing the risk of damage.
