Review (2/5): This seems like it would be a good idea
This seems like it would be a good idea, but it actually does not hold brushes well upside down or right side up. All my brushes just slip down a few seconds after I insert them. Also because the openings are quite big and the plastic grippers are not that grippy, you can't even use it to store already cleaned brushes. They just sink down if you put them in from the top.
