Using this automatic coffee stirring cup is a breeze. First, open the cup and pour in your coffee or other drink. Then, insert 2 AA/7 batteries (not included) into the battery compartment. Turn on the switch, and the cup will start stirring your drink automatically. When you're done using it, make sure to turn it off. Keep the cup away from water to avoid damaging the electrical parts. To clean the cup, simply wash it with mild soap and water and let it dry completely. Don't use abrasive cleaners as they might scratch the ABS material.
