Kensington Expert Mouse Wireless Trackball vs SlimBlade Trackball

The Kensington Expert Mouse Wireless Trackball and the Kensington SlimBlade Trackball are two stationary trackball mice designed for office use. The Expert is a wireless trackball mouse that comes with a wrist rest. It has a higher profile and has a scroll ring around the trackball. On the other hand, the SlimBlade is wired-only, with a low-profile design that doesn't come with a wrist rest or a scroll ring. It has significantly lower click latency than the Expert, but both mice have very low fixed polling rates and CPIs that can't be adjusted.
