Manufacturer description

The Dell KM5221W Pro wireless keyboard and mouse combo pairs a full-size plunger-key keyboard with a 4000 DPI optical mouse over a single 2.4 GHz USB receiver, so you occupy one port instead of two. Both pieces come in a matching white finish that suits a bright desk setup or a shared office workstation rather than an RGB gaming rig. The keyboard carries dedicated volume control and a mute hot key, which keeps call and media adjustments off your screen and under your fingers. Plunger switches give a quieter, lower-profile typing action than mechanical keys, a practical fit for open offices…

Dell's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.
