Before the product is shipped out, our warehouse staff will check the product to ensure there are no errors before packaging and shipping. However, since the transportation is completed by a third-party logistics company, which is beyond our control, we will not assume responsibility for damage or damage to the product's functionality due to transportation reasons. Therefore, please check the product carefully when signing for it, especially when the outer packaging is damaged and check if there are any missing items before signing. If there is a discrepancy in the quantity, please do not sign for it and contact us. If there is an inaccurate quantity after signing, we have the right to refuse to handle it. Please pay attention. We do not assume the freight costs for customers to return (refusing to receive payment items). If you need to supplement accessories, you need to supplement them when you next order. If you need to supplement immediately, you need to bear the freight costs yourself.
