Before confirming the production order, we will provide the rendering picture and 360-degree panoramic video, so that customers can fully understand the style and structure of the machine, so as to ensure that the actual machine meets the requirements of customers, so as to avoid the discrepancy between the real object and customers' imagination caused by various communication deviations. UTECH technical support is designed to help you make the most of the machine. A variety of technical files and installation videos will be placed in the U disk and shipped with the machine. Our technical experts can provide online remote support and training, and contact UTECH technical support experts in real-time for remote diagnosis. Door-to-door service is also available.
