3. Why does Cezhen need a valid proof of purchase?

Cezhen must confirm that the product is in the proper limited warranty period. We also need to verify that your product was purchased from an authorized seller of Cezhen products.

Products purchased from unauthorized dealers are often used, forged, repackaged, faulty, or parallel. The design and packaging of these goods may also not be applicable in your country and do not comply with safety regulations.
