not for noting but the shaker cups suck for one reason
1 reason only
they are pretty good with leaks, rarely do i get them sometimes just lid isnt tight enuff etc
BUT MY 1 problem ISSSS
the propellar thing that is there to help mix things up is HORRIBLE it needs more prongs or a mesh net type of thing
i used these pinnacle ones for 3 years they were the best thing ever had a net like design and totally grinded up all my shakes like a blender. if they didnt get all smelly and slowly falling apart id still use em
