The personal blender market is full of poorly considered products with blending cups that are not designed for drinking. The cup rims are threaded for blades to attach, but do not provide a smooth drinking experience when placed on the lips. The cups are too large for a comfortable grip and are made worse by tabs or ribs that stick out to engage the blender. The Boss To Go cups are smooth lipped for drinking without any tabs or ribs. The result is a functional drinking cup with traditional glassware esthetic, optimized for blending performance and ergonomics. 1,000 W motor power and the Kinetix blade and bowl produce Superblender fineness. Smoother smoothies from a smoother cup.
