It works great. But be careful, it might look small but it's powerful. Put your juice into something that is tall and has lots of room above the juice before you turn the little mixer on .. if your container isnt tall enough with lots of open space above the juice then the juice will splatter out and hit you in the face (can you tell that's what happened to me the first time I used it? LOL).
I have some 60ml, and 120ml bottles, so should be able to do it, however, I like my juice stirred, not bruised.
