Its hotswap PCB allows changing switches without soldering, supporting various silent and tactile switch types.

Key Features

• Three connection modes: wired via USB-C, Bluetooth 5.1, and 2.4 GHz wireless, offering flexibility for different setups.
• Polling rates vary by mode, with 1000 Hz wired for low latency, and lower rates for wireless connections, affecting responsiveness.
• RGB backlighting with all-LED illumination allows basic customization of lighting effects.
• Hotswap PCB supports easy switch replacement, enabling users to tailor typing feel without soldering.
• Preset multimedia key combinations provide quick access to common functions without dedicated keys.

Build Quality

• Aluminum top plate and ABS bottom provide a sturdy, stable frame.
• Plate-mounted switches improve stability and reduce wobble during typing.
• Thick dye-sublimated PBT keycaps resist shine and wear, maintaining legends over time.
• Double-layer silicone sound absorption reduces typing noise for a quieter experience.
• 3-way cord channel allows cable routing from left, right, or center, aiding desk organization.
• Two-step adjustable kickstand offers ergonomic angle options.

Typing Experience

• South-facing switch orientation supports compatibility with certain keycap profiles and reduces interference with larger keycap designs.
• Available switch options include silent and tactile variants, catering to users who prefer quieter or more responsive feedback.
• Sound absorption and PBT keycaps contribute to a muted, less harsh typing sound.

Connectivity

• Wired USB-C connection provides the fastest response and full NKRO (N-key rollover) for gaming or fast typing.
• Bluetooth 5.1 offers convenience for mobile or multi-device use but has a lower polling rate, which may affect input lag.
• 2.4 GHz wireless mode balances latency and convenience, with a polling rate between wired and Bluetooth.

Trade-offs

• Lower polling rates in wireless modes may not suit competitive gamers requiring minimal input delay.
• Multimedia keys are accessed via key combinations rather than dedicated buttons, which can slow workflow for some users.
• Unknown battery life and firmware customization options limit assessment of wireless endurance and remapping flexibility.
