Vitamix CIA 1709 Professional Series Blender - Brushed Stainless - As the Vita Mix CIA 1709 Professional Series Blender - Brushed Stainless was designed by top chefs, meaning actual, working chefs, you can trust that when you need something mixed, ground, or blended, you know you can get the job done.

The stainless steel housing isn&#039;t just there for looks, as any chef will tell you that toughness equals longevity, and stainless steel is in it for the long haul. Open up one of the three included cookbooks and let CIA-trained chefs show you how to make the most of this versatile, countertop blender.
