The Logitech G900 Chaos Spectrum is an ambidextrous wired/wireless gaming mouse designed for professional-level performance and customization. It uses durable ABS plastics, PTFE skates, and reinforced internal components to withstand extended gaming use while offering customizable RGB lighting and modular button placement. Key features include Logitech LIGHTSPEED wireless technology, a high-precision PixArt PMW3366 optical sensor, and a removable micro-USB cable for wired or charging use. The design emphasizes low weight, high polling rates, and long button life for reliability in esports and intensive gaming.

The Logitech G900 Chaos Spectrum can be identified by the model number (M/N M-R0054). The model label is on the underside of the mouse. This label lists the model (M/N), part (P/N), and serial (S/N) numbers.
