The Blendtec Classic 575 Blender -WildSide+Jar (900z) and FourSide Jar (75oz) Bundle is a blender that is powerful and gets the job done well and fast. This is a combo with dual containers and is easy to use and clean. Easy Blending Cycles one touch buttons with four pre-programmed cycles and five speed manual control allowing you to achieve a variety of textures.
