Glad we ordered the right container. In our move, I dropped our old one and the weighty ceramic blade base caused the plastic around it to shatter. My mistake by dropping it. The new one fits and works perfectly. Our old container was about 8 years old (9?), and had become hard to see through. We grind nuts, rice, and all kinds of grains for flours. In addition to smoothies, soups, tomato sauce, my wife uses it pretty much daily. Great replacement container.
I have been lucky to own a Vitamix blender. My first was a gift from Mom, and it changed my life, literally. I can't imagine not having smoothies everyday!
