The 48 oz. container is far superior when it comes to making small batches. This is because the tapered, narrower base makes it easy for this container to create a vortex with less ingredients than is necessary with the 64 oz low profile containers. In addition, the 48 oz container is large enough for all but the largest of recipes. I really wish all Vitamix blenders came with the ability to choose which size container that you prefer. My dream combo would be an A3300 blender with the tall thin classic 64 oz. container that comes with the 5200. I realize that the Classic 64 oz. container does not work with Ascent blenders; I just wish that it did.

I have the tall 64oz container and wanted something a little smaller. This does the trick. Came with the smaller tamper and works great! Love my Vitamix!!

I just recently purchased a new Pro Series 750. Immediately I realized the included 2L container would provide much more capacity than needed so I purchased the .9 and 1.4L containers. The .9L container fits rather nicely on the base (inside the fingers) with just a little play as compared to the 2L. It has a quality feel to it, thick plastic, stable handle, fairly confident seal on the lid. The 48oz however has a lot of play and spins roughly 1/4" on the base when power is applied. Also, the plastic handle is thinner so it has a little play to it as well. It is designed to fit over top of the fingers on the base much like the 2L however the plastic base of the container is more a rounded square and overshoots the fingers on the motor base I was hoping it would seat as nicely as the 2L and have the same quality feel however it doesn't. I don't understand why the 1.4L container doesn't use the same rounded corner concave square base as the 2L. For the price of the container I expect a better design.
