Overall good purchase as the plastic canisters were not holding up to our daily use.  Prefer any non-plastic option generally.  My only complaint would be that the narrow shape/size difference does require a bit more agitation with the blend stick to get going.  Particularly if it’s a hearty smoothy full of greens.  It’s a manageable issue and the metal far outweighs the cons of the plastic container.  Also for those concerned about noise we have found this to be less noisy than the plastic containers.  Fwiw.
