Back when I used computers for work I exclusively used trackballs because they’re better for my carpal tunnel. I switched back to mice because they’re better for games and I rarely use the computer for hours at a time anymore.

I’ve been wanting a manufacturer to make a good combo trackball/mouse for ages. I think it could be an amazing input device if you could use the mouse part for big movements and the trackball for fine control.

I found one on AliExpress, but it had poor quality sensors, a tiny ball, and no ability to adjust dpi independently.
