We brought the Vitamix stainless steel container in October 2021 and thrilled the container has the narrow base which blends smoother than the wider base containers.   We use it daily for making smoothies and the consistency of the smoothies is much better than smoothies blended in the short, wide based 64 ounce container.   The consistency of smoothies from this stainless steel container is par with smoothies made in the tall, narrow based 64 ounce container but comes out much cooler!   We haven’t seen any fading of the measurements inside the container which we attribute this to hand washing, and not blending any acidic ingredients, but, no fade issues.  Sound level is about the same as the plastic containers, LOUD.   The container is expensive but given we now use it daily and it looks great, and no clouding, we are thrilled with it. 

Thank you Vitamix.
