I have had this container for a couple of weeks now, and I am very satisfied. It is sturdy, fits my Vitamix perfectly. The best part is that I can now blend hot drinks and soups in my Vitamix without concern about plastics leaching into my food. Additionally, the container is so strong and sturdy that I cannot imagine I will ever need to purchase another one in my lifetime, unlike the plastic version which came with my Vitamix when I first purchased it. Overall, I am very happy with this container!
