I’ve been a Vitamix fan for years.  I make a green smoothie every morning for me and my husband in the large container.  Sometimes I put the ingredients inside the container the night before and add the rest to blend in the morning.  With the large container in the fridge, I can use my new small container in the evening to whip up a healthy treat.  I’m enjoying the versatility of 2 containers that are different sizes.  Vitamix rocks!
