The blades on my Vitamix 750 were covered by the recall. I sent my old container back and, instead of just replacing the blades, Vitamix sent me a new container, which has a new design. While this was nice of them, this new design has a bad leaking problem (it does not appear to be a manufacturing defect in the container — they just sent me a second container and lid, which has the same issue):
The lid relies on a double flange to create a seal. Unfortunately, at the point where the handle attaches to the container, there is a depression in the container's plastic, on the inside, just below the lip. As a result of this depression, liquid can quickly pass by the lower flange, leaving only the upper one as a seal. In addition, the depression slightly extends to the lip, allowing the liquid that has passed by the lower flange to penetrate the upper one.
This makes absolutely no sense to me — how can Vitamix not understand that you can’t seal a non-round container with a round lid? Frankly, it boggles the mind that Vitamix could have made such an obvious engineering error in the design of their new container.
Has anyone had a similar experience?
