Through liquid simulation, your Cyclone Cup is proven to mix better than today's leading shaker bottle. Today's leading shakers utilize free floating mixing elements, such as wire whisk balls. These flow with the liquid inside. As a result, mixing is not as efficient. Your Cyclone Cup however utilizes patented Cyclone technology. The Cyclone inside is stationary and moves against the flow of your ingredients. This maximizes the stream of kinetic energy for superior mixing every time. BPA Free.
