Verdict

The Logitech G603 Lightspeed is a high-performance wireless gaming mouse featuring the HERO optical sensor with a sensitivity range of 200–12,000 DPI and a 1ms report rate via Lightspeed technology. It offers dual connectivity through both a 2.4GHz USB receiver and Bluetooth, powered by one or two AA batteries that deliver up to 500 hours of use in 'HI' mode or 18 months in 'LO' mode. Its primary advantages include its exceptional battery efficiency, lag-free wireless performance, and an ergonomic right-handed design that allows for weight customisation. However, it is noted for being relatively heavy at 135.7g with two batteries, lacks RGB lighting, and features a smooth plastic finish that some users find slippery compared to rubberised alternatives.
