This Purple Heart edition uses Milk V2 switches and bear-patterned dye-sublimation PBT keycaps, and it comes with a soft-touch wrist rest. You can connect over Bluetooth, 2.4G wireless or a USB-C cable. The keyboard pairs with up to 5 devices and works with Windows, Mac, Linux, iOS and Android. A built-in 4000mAh battery means you charge it less often. The typing feel comes from a gasket…
