When the car stopped, the heating pad moved forward and my coffee poured out. This is because it is impossible to fill the cup holder with water completely. I put a bottle of cold water in the machine, press the cold button. The water bottle got warm. Cooling water temperature cannot be maintained. I sent it back after several days of testing. upset.
