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.

I bought this 48oz container because the 64oz one that came with my 7500 is too large for smoothies and small servings of frozen desserts. The smaller container great for smoothies, nut butters, sauces, and hummus. I give 4 stars instead of 5 because it's hard to clean. For anything thicker than a smoothie, food gets stuck to the metal ring under the blades. Blending with dish soap for 30 seconds, as recommended, doesn't get all the grime. I've tried soaking it in vinegar, to some avail, but for the most part I've resigned myself to having a not entirely clean container.
