After more than a decade of mice and trackpads, Logitech has brought back the classic trackball design in the form of MX Ergo, an advanced wireless trackball designed with a focus on both comfort and precision. Inspired by feedback from Logitech trackball users over the years, MX Ergo features an adjustable hinge for comfortable ergonomics and a precision tracking feature that allows users to quickly switch cursor speeds for finer-grained navigation.
