Query: Perfect for Mixing Drinks

I use this for mixing up either my own homemade juice from the juicer (no water or milk, just juiced fruits and vegetables) and it really gets everything mixed up well. Since the juicer can only do one piece at a time, my drinks tend to get layered by the order in which I juice each piece of fruit or vegetable, and straws aren't always strong enough to mix up the juice well. I also use this for mixing powdered mixes with water or milk, which I prefer to drink cold even though warm water mixes them better. I never need to heat up my drinks anymore in order to mix them - I love this product. I received the purple color by random for a few dollars less than being able to choose my color, and it was entirely worth it. All three pieces are very easy to clean with soap and water, and a sponge every few uses on the ball.
