DELL Pro Premium Compact Mouse - MS7421W - Graphite Black

Ultimate convenience
Always ready: Enjoy a hassle-free 6-monthi long battery life when you charge it fully in just 3 hours. A quick two-minute charge via the included USB-C cable will guarantee you a day’s work of uninterrupted performance.
Seamless connectivity: Connect and switch effortlessly across three devices with the dual mode RF 2.4 GHz wireless and Bluetooth connectivity.
Thoughtful design: Never lose the universal pairing receiver thanks to the dedicated dongle slot which allows you to conveniently keep it within the mouse when not in use.

Empowering productivity
Simple Management: Instantly access your most frequently used commands or applications by configuring the 5 programmable buttons via Dell Peripheral Manager (DPM). With DPM, you can easily pair your devices, program shortcut buttons, adjust DPI, check battery and connectivity status and the latest firmware updates — whatever suits your needs.
Precise Tracking: Sculpted with a patterned grip in cool platinum silver, this little wonder offers 4000 DPI, adjustable via DPM to three other preset DPIs at 1000, 1600 and 2400. Navigate with ease across ultra-wide and high-resolution displays and multi-monitor setups.

Service you’ll love
Peace of mind: Minimize the risk of downtime with the three-year Advanced Exchange Service which ships you a replacement mouse the next business day if needed, offering you added peace of mind.
