TECKNET Ergonomic Vertical Wireless Mouse — Bluetooth + 2.4GHz with USB A Receiver, 4800 DPI (6 Adjustable Levels), 6 Buttons, Quiet Clicks, 12 Months Battery, Wide Compatibility

Comfort-focused vertical design for right-handed users that positions your palm near-vertically to reduce wrist strain from prolonged inverted mouse use (Note: Mouse is designed for right-handed use only). Built with optical tracking and an upgraded high-performance chip, this wireless mouse moves smoothly across a variety of surfaces. Adjustable DPI & indicator: Choose from 6 DPI settings — 4800/3200/2400/1600/1200/800 — to suit different tasks. When you switch DPI levels the LED will flash; the number of flashes corresponds to the selected DPI. Quiet operation: Left and right clicks are engineered to be nearly silent, making the mouse suitable for quiet environments such as libraries. Other function buttons are not silent. Connectivity and controls: Supports Bluetooth and 2.4GHz wireless operation with a USB A receiver. The mouse features 6 buttons for navigation and control. Power management & battery: Long-lasting performance with up to 12 months battery life (requires 2 AAA batteries, not included). The mouse automatically enters deep sleep after approximately 10-30 minutes of inactivity to conserve power and can be woken by pressing the left or right button. When battery is low the LED will blink; using branded batteries is recommended to extend service life. Compatibility: Works with Windows, Mac, Chrome and Linux systems (note: side buttons are not compatible with macOS).
