I tested our brand new Vitamix dry container for teflon bearing debris by running it on 10 for 1 minute using clear water and then emptying into a white bowl. The container repeatedly generated dark-rose colored debris (see photo). I have returned the container under warranty.

Made bread dough and the cleanup was terrible. The dough got stuck under the blades and I had to get a toothbrush to get all the dough out. Took forever to clean.

Bought this for the purpose of making powdered sugar and grinding fresh coffee. I have made powdered sugar out of coconut sugar (pictured) and organic cane sugar. Both blend up beautifully. I can't tell the difference between the powdered cane sugar and store bought. Love that this makes organic powdered sugar affordable and easy! Grinds my coffee beans up perfectly with little effort. Have also made oat flour with this. Well worth it. Very satisfied with what this can do and how well it does it compared to using just the regular container. Highly recommend if you're looking to grind dry stuff.
