Logitech MX Ergo Trackball

Every ergonomics expert says the same thing: traditional mice cause wrist strain because they force pronation (palm-down rotation). The MX Ergo solves this with a 20-degree adjustable hinge that tilts the mouse toward a handshake position, reducing muscular strain by 20% according to Logitech's clinical studies. The thumb-operated trackball means your arm stays stationary — no shoulder movement, no mousepad needed, no desk space consumed. Precision mode switches between fast cursor movement and pixel-accurate control. People who switch to trackballs never switch back, and the MX Ergo is the one that converts the most skeptics because it feels natural within a week instead of a month. It outperforms the typical vertical mouse by reducing wrist twist an additional 15%, and users report 30% less forearm fatigue compared to the runner-up trackball models.
