Overview

The Lenovo 300 Wireless Mouse (GX30K79402) is a no-frills compact mouse built for users who need a reliable pointing device they can toss in a bag and forget about. Measuring just 3.86 x 2.2 x 1.26 inches, it is noticeably smaller than full-size desktop mice, which makes it well suited for travel and cramped workspaces. Its ambidextrous shape means it works comfortably regardless of hand dominance, and the 2.4 GHz nano USB receiver provides a stable wireless connection without the complexity of Bluetooth pairing.

Under the hood, the optical sensor operates at a fixed 1000 DPI — adequate for everyday productivity tasks like document editing, web browsing, and presentations. Battery life is a standout feature: a single AA battery can power the mouse for up to 12 months, so you rarely need to think about replacements. The trade-off for this simplicity is a lack of advanced features — there are no programmable buttons, no DPI toggle, and no rechargeable battery. For professionals who value portability and dependability over customization, the Lenovo 300 delivers exactly what it promises at an accessible price point.
