TECKNET Vertical Ergonomic Wireless Mouse — Bluetooth + 2.4GHz USB-A Receiver, 4800 DPI (6 Levels), 6 Buttons, Quiet Clicks, 12-Month Battery

Designed for comfortable, right-handed use, this TECKNET vertical mouse places your palm nearly upright to reduce wrist strain during extended tasks. It uses optical tracking with a high-performance chip to glide smoothly across a variety of surfaces. DPI can be adjusted across six preset levels (4800/3200/2400/1600/1200/800); when you switch DPI the LED will flash, with the number of flashes indicating the selected level. The left and right buttons produce nearly silent clicks so you can work in quiet environments such as libraries without disturbing others (other function buttons are not silent). The mouse supports both Bluetooth and a 2.4GHz connection via the included USB-A receiver and provides six buttons for common navigation and shortcut use. Compatibility extends to Windows, Mac, Chrome and Linux systems (note: side buttons are not compatible with macOS). To save power, the mouse automatically enters a deep sleep mode after approximately 10–30 minutes of inactivity; press either the right or left button to wake it. Battery life is rated up to 12 months under typical use. Power requirements and warnings: requires 2 AAA batteries (not included). For best longevity, TECKNET recommends using branded batteries. When battery power runs low the LED will blink to alert you.
