This works much better than the Magic Bullet at smoothie without any fuss or interference.  But holy cow it’s loud!  Also, cleaning the blade is quite a challenge.  Mine has literally started smelling like rotted food no matter what I do to clean it - and I’ve tried a lot! I think I literally have to replace it.  I think the high pressure created during blending must’ve forced  food particles into the crevices of the blade gears or something.
