Wildside is a patented Blendtec mixer, compatible with all Blendtec blenders.
The jug is designed to best mix the ingredients with 25% increased efficiency to mix frozen ingredients. The blunt blade is 80% stronger than similar blades.
The Wildside jug has a fifth side that allows for larger and faster mixes. Two vertical elevations on the inside of the pit help the blender to accelerate further.
