The Dell MS7421W is a wireless mouse designed to enhance productivity when working with multiple devices. It can connect either via a USB wireless receiver or directly via Bluetooth to PCs, laptops, and compatible mobile devices. Pair the mouse with up to three devices—two via Bluetooth and one via USB—and easily switch between them with the press of a button—multitasking has never been easier. When not in use, simply store the USB receiver in the mouse's housing to prevent it from getting lost. The MS7421W is also very energy-efficient: with a single battery charge, you can use it for up to 6 months.

An input device for all your computers—the Easy Switch technology makes it possible. Keyboards and mice with Easy Switch technology can be paired with multiple computers and seamlessly switch between them at the touch of a button. Multitasking has never been easier.

Enjoy plenty of freedom of movement without the hassle of tangled cables: USB wireless input devices establish a wireless connection to the receiver, which you plug into an available USB port.
