Once we start to make samples or make mass production, we will always think around you, keep communicating with you constantly, try our best to optimize the settled solution. Besides, we will report the production schedule, battery situation and the production site to you by video at anytime, so that you can fully know the situation of your product in your home. The video will be exactly the same as the video of “classic cases” on this website. In a word, everything can be seen, and everything is under your control.
