wireless mouse with Usb mini receiver unites whisper-quiet left and right buttons with a 250 Hz high-return microchip that makes every click feel instant and every scroll glide faster, while 2.4 GHz frequency-hopping technology creates a rock-solid link that shugs off Wi-Fi routers, smartphones and every other signal in the room. The sculpted ergonomic shell melts into either hand, its satin surface inviting long sessions of work or play without cramp or fatigue, and an intelligent 1 600 Dpi optical sensor tracks flawlessly on wood, glass, fabric or desk pads, letting the cursor snap to icons, headphones or spreadsheet cells with pixel-level precision. Plug the tiny receiver into any laptop, Pc or notebook and forget about it, the mouse pairs in seconds and stays connected up to ten meters away so you can lean back, pace or present without drops.
