Kensington Pro Fit Ergo Vertical Wireless Trackball

The Kensington Pro Fit Ergo Vertical Wireless Trackball is a specialized computer input device designed for ergonomic comfort, featuring a 60-degree tilt to promote a natural 'handshake' wrist position. The product is manufactured in China, which is standard for the majority of Kensington's electronic peripherals.

Kensington has a storied history in the computer accessory market, founded in 1981 in New York by Philip Damiano. The brand became famous for its security locks and early trackball models like the Turbo Mouse. Over the decades, it has evolved into a global leader in desktop productivity and laptop security. Ownership of the brand shifted early on; it was acquired in 1986 by ACCO World (now ACCO Brands). As of 2026, Kensington remains a core division of ACCO Brands, a major American manufacturer of home and office products based in Illinois. The brand continues to focus on 'The Professionals' Choice' philosophy, integrating ergonomic research into its hardware designs.
