What are the YoYoExpert bearings like?

Strangely enough, I had originally done this because of a video done by André Boulay and posted in the “Learn” section of this site! In the video, André puts a drop of thin lube on the side of the bearing, with the shield still on, and spins it. This actually more or less worked for me until now.

He spins it so it gets inside the shield. Not sure why it works that well.
