I bought my new Dry Grains Container to go with my Vitamix base. It has been invaluable in grinding wheat during these shortages of whole wheat flour. I love it and would highly recommend it to others. I am careful as I have heard one can burn out the motor if you grind on a high speed for too long. So I have followed the instructions and only grind 2 cups at a time for 1 minute. It makes wonderful flour. Thank you for a great product. Well worth the investment.
