I bought the dry grains container specifically to make flour from wheatberries. There are a lot of reasons to avoid store bought flour, and there are a lot of ways to make flour at home. I already had and adored the Vitamix, so I thought, why not add this to my arsenal? But immediately upon using the dry grains container for my wheatberries, I noticed that it started to look textured on the bottom third of the container. Look at the photo below. This texture is happening because as the grains knock into the inside walls of the container, they make tiny dents / chips in the plastic. I am nervous that microplastics are entering my food because of this. I am a loyal Vitamix user and always tell people to get a Vitamix 5200 as opposed to Ninja or other lesser blenders. The 32-ounce Dry Grains Container is the only thing that makes me pause and say, "...but there is this issue with the plastic pockmarking and potentially releasing plastic particles into your food." I don't have this problem with the regular container. For making flour from wheatberries, I do not recommend this product and instead would urge you to spend the money on a home mill, which I will be doing ASAP.

Good size, but several disappointments. The handle is unlike the 64 oz container's, and has a cheap feeling with sharp edges and a hollow handle area which collects crud and is not easily cleaned. The container's base is narrow and unsteady, fitting inside the motor base's guides, instead on the outside of the guides like the 64 oz container. The 64 oz container is purposely rounded overall, with ingenious patterns of circulation, but the 32 oz container is rectangular inside, with a rounded lip and lid similar to a 1972 Sunbeam blender. Almost as if this container was manufactured by some other company.

Replacement 48oz container I've used my blender for several years and needed a replacement container. Got the 48oz instead of the 64Oz. I really love the size but unfortunately the handle is a poor design. It's hollow which can make clean-up a chore. Also, because it's hollow, it is open at the top so there is no place for your thumb to rest for stability.
