The mark consists of a two-dimensional stylized drawing of a handheld device having a generally T-shaped configuration with a horizontal barrel portion and a vertical handle portion. The barrel portion is predominantly black and gray and includes a circular opening at one end, hexagonal surface patterning, and linear vent-like elements. Orange accent bands appear around portions of the barrel. The handle portion is predominantly black and gray and includes geometric paneling and surface contour lines, with an orange button on one side of the handle and an orange accent at the base of the handle. Three small blue circular indicator lights appear on the upper portion of the handle. Shading, highlights, and line work indicate surface features and design details only and do not indicate three-dimensional shape or depth. The mark is a flat, two-dimensional design and does not represent a three-dimensional product configuration.
