Dear customer, we are very sorry that we did not bring you a good purchase experience due to the difference in product model cognition and the loss of some parts (but it does not affect the use) caused by the transportation process. Here we sincerely apologize to you. We also reflect on where we fell short. Finally, thank you for pointing out the mistakes in our work, so that we have the opportunity to correct and improve the work to do better. Wish you a happy life!
