## Overview
It features Razer HyperSpeed wireless technology with 4K Hz polling, hot-swappable switch sockets, a Command Dial, and an OLED display. This keyboard is built for enthusiasts who demand the best in wireless performance and personalization. The gasket-mounted FR4 plate, tape-reinforced PCB, and screw-in stabilizers deliver a refined typing feel and sound profile that rivals custom builds.

## Connectivity & Compatibility
The HyperSpeed mode provides near-zero latency for competitive gaming, while Bluetooth allows easy switching between a PC, tablet, and phone. Compatibility is primarily with Windows 10/11 systems for full software control via Razer Synapse. Bluetooth works with any device supporting HID keyboard profiles. Note that 4K Hz polling is only available in HyperSpeed wireless mode, not over Bluetooth or wired.

## Product Info
It comes with a 2-year warranty through Razer's official channels. The box includes the keyboard, a plush leatherette wrist rest, the HyperPolling wireless dongle, a USB-A to C cable, a keycap and switch puller, three spare Orange Tactile switches, multilingual documentation, and Razer stickers. Its combination of 4K Hz wireless, hot-swap capability, and an integrated OLED display sets it apart from most rivals.

## Best Use Cases
Competitive gamers: The 4K Hz wireless polling ensures input lag is virtually imperceptible, giving an edge in fast-paced shooters and fighting games. Pair with a high-refresh-rate monitor to fully benefit. Customization enthusiasts: Hot-swap sockets let you experiment with different switches without soldering. The OLED display can show system stats or custom GIFs, and the Command Dial can be programmed for volume, zoom, or app-specific shortcuts. Wireless operation eliminates cable clutter.
