Dell Premier Rechargeable Wireless Mouse MS7421W
The Dell Premier Rechargeable Wireless Mouse MS7421W is built for professionals who need a wireless mouse that stays charged and ready across a full work year. It connects to three devices via 2.4 GHz and Bluetooth, recharges fully in two minutes, and runs up to six months between charges.
Why this product
6-month battery life per charge
A single full charge powers the mouse for up to six months of typical use, and a two-minute quick charge delivers a full day's work.
Connect to three devices at once
Switch between computers, tablets and phones using 2.4 GHz wireless or Bluetooth 5.0 without manual re-pairing.
Seven programmable buttons
Customise button functions and DPI settings (1000 to 4000) using Dell Peripheral Manager on Windows, or by direct button adjustment.
Compact and right-handed
Measures 4 inches long and 2.4 inches wide, sized for standard or smaller hands with ergonomic curves.
Three-year hardware warranty
Includes Advanced Exchange Service for three years, so a faulty unit can be swapped before you ship the broken one back.

- Windows-based professionals using custom button and DPI profiles through Dell Peripheral Manager.

Trade-offs
- Left-handed users: this mouse is shaped for right-hand use only.
- Users requiring profile management on macOS or Linux: custom button and DPI settings are Windows-only; other platforms can adjust DPI via on-device buttons.
- Gaming or high-precision work: optical tracking and a maximum 4000 DPI suit office productivity, but not competitive gaming or CAD work.
- Organisations outside Dell's support infrastructure: Advanced Exchange Service is limited to Dell's enterprise and partner networks.
