Logitech describes the G900 Chaos Spectrum as its "best gaming mouse yet" designed for maximum performance and comfort for long gaming sessions. It has all of the expected features of a high end gaming mouse -- an advanced optical gaming sensor, ambidextrous design, customisable lighting, mechanical pivot button design and it is lightweight. But the real standout is its wireless technology, which promises to be professional grade, lag-free and faster than a wired mouse.
