only one cup works
Only one cup works with the nutribullet. Why would one cup work and not the others.
I only use the large cup in general and found that this cup only works when one particular cup hook is pressed into one particular part of the base. Why this is so I don't know. I rotated the cup around to hit all 3 of the base connectors which is how I found this out. So now I make sure to just put the cup on in the right spot on the base.
