My VitaMix is 20 years old. Wonderful appliance. The original container developed a crack and I lived with the leak for several years due to my budget. Finally was forced to look into buying another, as the leak increased. Didn't realize there were different sizes. I chose a smaller one because it was cheaper. So glad I did. It meets my needs, plus it fits under the kitchen cabinet doors. I'm back to happily making smoothies every morning, and soups weekly.
