I have an original C series or TNC machine. I was always envious of the new low stature containers and when I noticed there was a 1.4l container available for my C series, I bought it. I have to say, it is nowhere near the quality of my original container. The clear plastic handle is quite thin and the lid is made from a hard plastic. This renders it completely inflexible and hard to fit.

I’ve had my vitamix for prob 7 years now, used for a few month period 4-5 times a week until I got frustrated that it would jam and would spin trying to make a simple smoothie. Constantly having to remove lid which was a pain and stir. Used plenty of liquid. Did not overfill. Pitcher quality is poor. Cloudy and stopped leaving it on counter because looked dirty. I agree with others about the plastic quality…finally just bought a nicer looking Bullet Blender.

We have had our Vitamix for 2 years and we love it. The only problem is the interior or the plastic container scratches and gets cloudy making it visibly unattractive. Only dish detergent is used to clean it. We only use vegetables in the blender and avoid seeds and acidic substances such as lemons. I'm not sure why this interior deterioration occurs. If you could make a glass or Pyrex container that would be wonderful. But the plastic just doesn't compare with the quality of the machine.
