Wireless 2.4 GHz connection with nano‐receiver — gives you freedom from cables and a stable connection (range ~ 8 metres) which is good for general use or working away from the PC.
Compact, lightweight and portable design — the small size (≈ mm) and light build make it easy to slip into a laptop bag or carry around; nice if you use a laptop or switch workspaces often.
Plug‐and‐play simplicity — no drivers or complicated setup needed, works across Windows / macOS / Linux (basically anything with USB) with minimal fuss.
Basic but reliable sensor & buttons — optical sensor at 1200 DPI (good for everyday tasks: browsing, documents, general work), and 3‐button layout (left, right, scroll) with a button life rated at ~3 million clicks — adequate for long-term basic use.
