We’ve bee Vitamix owners for over 10 years!  We purchased 3 as gifts for family.  We prefer the classic container to the shorter container as we’ve had trouble sometimes getting all of our veggies in our smoothies to chop up with the shorter container.  The classic container always works for us, no matter how much or what ingredients we are using!  We use our Vitamix daily and purchased the new container after years of stain marks building up on our old container.
