The Magnesium chassis and construction for the Starlight Phantom has been improved and refined in a multitude of ways. Structural support, wheel adjustments, base adjustments, click changes, and pcba changes were all made to create an even more polished feeling when holding the Starlight-12 in hand. The weight of the mouse has not been affected and we expect the Starlight-12 phantom to actually come in lighter than its predecessors.
