I bought this as a replacement for my original when necessary. The original is now over two years old, used at least 600 days and still in great shape. I am sure that the new one will be the same.
I bought the replacement container because I didn't take care of the other one like the manual said. Now, I know better and this will last me a long time!
I recently replaced the 64 oz. container for my Vitamix due to a crack in my old container. Online ordering made it a breeze and I received it approx. 7-10 days later. I use this at least 3-4 times/day making smoothies, sauces, dressings, etc. for meals. It is a Classic I can't live without!!
