First of all, OEM products usually attach their own trademarks or labels to the products, and will not remove or cover up the trademarks or labels of the original products. Secondly, OEM products are generally produced by other companies or factories, rather than having their own production facilities. Moreover, OEM products generally do not have their own independent brand official website or brand publicity materials, but rely on the official website or publicity channels of the original products. Finally, the price of OEM products is usually much lower than that of the original products, because OEM companies do not need to bear the R&D and production costs of the original products.
