It's like this.

But it didn't happen earlier. Maybe, I need to disassemble it and clean roller itself inside and metal axle under roller?

I have a little issue.
I got a used Free2 and recently I notice black spots on left side of the metal axle. When it happens, the roller feels sticky. When I remove this spots, it feels smooth again, but after 2-3 days spots come back again. Any ideas?

I have one. There are some unpleasant issues:
— it not supports Precision Touchpad drivers;
— scrolling isn't smooth like laptop's touchpad. Moreover that, the upward scrolling is jams sometimes;
— also you can get unexpected zoom when you scroll something to top/bottom and press ctrl key ...

I gonna make a board with this layout:. I wanna try shift keys next to spacebars, like in some old soviet computers, left-handed arrow keys and dedicated cut-copy-paste and undo/redo keys.
