We have received 2 emails said that meet this issue. This is a conversation between one of the customers and NP service. I asked him to sent a video to us to determine what the noise was, and asked him to confirm whether the express package was damaged or any dents. He said that the outer packaging was intact, so the package was not treated rudely. According to the sound of his video, it is easy to judge that it is an extra screw. I asked him to take apart to take a look inside, after we allow it, it will not affect the warranty. He found an extra screw,
@mdb_talon We agree that you take it apart and take a look inside, it won't affect the warranty. Sorry for the inconvenience. I guess there is an extra screw inside. Please take it apart and take it out.
It should have been accidentally put in an extra screw, we will pay attention to it next time. Thanks for the feedback! !
Thank you for tag me,
