The 4 root Mechanical Keyboard from Das Keyboard is a full-sized keyboard with a US-layout featuring 104 keys. It's built with Cherry MX Blue switches that provide you with a responsive typing experience thanks to its tactile bump. For your convenience, the root has dedicated multimedia keys as well as a large volume knob that you can use to quickly adjust your audio settings. Once connected, it supports full N-key rollover via USB, so your inputs will be precisely and accurately recognized regardless of how fast or how many keys you press at once. Additionally, it has a two-port USB 2.0 Type-A hub that you can use to connect devices such a flash drive, mouse, and headset. Unlike other keyboards that use flip-out rubber feet, the root has a magnetically attached footbar, which also doubles as a ruler.
