Video summary
A designer's first ergonomic trackball, reviewed after enough use to judge comfort rather than just features. Her starting point is wrist fatigue: she moves a mouse around a screen all day, and switching to a trackball that stays put has already made a difference at work.
The video covers the setup she relies on: a stable surface rather than a mouse pad, the thumb ball for cursor control, left and right click positioned for a natural hand position, a scroll wheel, forward and back buttons, and a silent click that suits late-night work. Because the mouse does not travel, she also uses it away from a desk - in bed or on a sofa, wherever there is a flat spot.
Other details: three connection channels for switching between devices, four RGB modes with a light button, five scroll-speed levels set from the mouse itself, roughly a month of battery, a one to three hour USB-C charge with a red indicator while charging, and a ball that pops out through the base for cleaning.
