Before the production of each food trailer, we will double check the product design drawings with the customer, determine the dimensions and details of each part, the specifications, models, and equipment dimensions of each internal device. Before shipment, we will also have the customer conduct a video inspection to ensure that there are no issues before shipping. At that time, the purchase of these devices was with your consent. Normally, this is not our responsibility, and we should not have made any compensation. However, after Alibaba's mediation, we have already provided you with corresponding compensation in a humanitarian manner. We hope you can understand.
