Refined, with a high-quality finish and a convenient non-slip scroll wheel, M300 transmits using Rapoo's latest and powerful multi-mode wireless featuring Bluetooth 3.0, 4.0 and 2.4 GHz. The comfortable compact design is boosted by a ‘silent click’ feature, which gives you freedom and a piece of mind since disturbing those around you is no longer a concern. To suit different preferences, M300 Silent features a high-performance sensor, fully adjustable from 600 to 1600 DPI. The included Nano USB receiver can be stowed securely and conveniently within the base of the mouse. To top it off, Rapoo’s power-saving technologies offer up to 9 months’ battery life.
