I LOVE this stainless-steel-container!! It is so CLEAN and makes me feel better not mixing in a plastic based container.  It is just healthier to mix in this container!!! At first, I was a bit uneasy about not being able to see the mixture as it was being mixed, but I got over that quickly and just peak through the top!!! It is super easy to clean and it stays clean looking!!! As all of my Vitamix products do, it works wonderfully and powerfully to make splendid pureed products.....
