Shaker cups differ from traditional cups or water bottles because they contain a mixing mechanism to blend the ingredients. There are several types of mixing mechanisms: ball or propeller-shaped agitators, built-in screens or strainers, and even self-contained mini motors. All shaker cups use our patented wire whisk—the mixing device that revolutionized the handheld mixing industry. Made from 316 surgical-grade stainless steel, the whisk cuts through even the thickest ingredients (think bananas, nut butters, dense protein powders, honey, syrup, and more), whipping around inside the bottle to reach every last bit of the mix-ins and blend the smoothest possible shake. Plus, it can stay in the bottle while you drink—the whisk will never rust, chip, or peel, nor will it tumble out of the drinking spout.
