⚡ Key Features

• Pairs to two machines at once — Bluetooth on one, the 2.4GHz USB-A receiver on the other — and slides between them without re-pairing
• Bluetooth 5.0 and legacy Bluetooth 3.0 support means it also connects to older laptops and tablets that never got a 5.0 radio
• Five DPI steps from 800 up to 4000 let you drop to fine precision for spreadsheets and spike to fast travel across a large display
• Runs for up to 18 months on a single AA cell, so there is no charging cable and no dead mouse mid-deadline
• Auto-sleep after five idle minutes is what stretches that AA cell so far
• Six buttons including dedicated forward and back thumb buttons for browser and file-manager navigation
• Micro switches rated to 3 million clicks for daily office duty
• 30° handshake angle with contoured grips and a matte finish keeps the wrist neutral over long sessions
• Works across Windows, macOS and ChromeOS, so it moves between a work laptop and a home desktop
