Key Features

• Hot-swappable switches allow easy customization of typing feel without soldering, compatible with most MX-style 3-pin and 5-pin mechanical switches.
• Bluetooth 5.1 supports connection to up to three devices, enabling quick switching between smartphone, laptop, and tablet.
• Full 100-key layout with a relocated Delete key offers access to essential keys while saving desk space.

Build Quality

The keyboard comes in plastic or aircraft-grade aluminum frame options, balancing durability and weight. An inclined bottom frame improves typing comfort over long sessions. Keycaps are ABS, which may wear faster than PBT but support the included backlighting well.

Typing Experience

Users can choose between Gateron Red, Blue, or Brown switches, covering linear, clicky, and tactile preferences. The hot-swappable feature enables easy switch replacement or upgrades. The keyboard’s layout and keycap sizing support efficient typing, though ABS keycaps may feel less premium.

Connectivity and Compatibility

Supports both wired USB Type-C and wireless Bluetooth modes. Compatible with macOS, Windows, Android, and iOS. Mac users benefit from dedicated multimedia keys. Linux support exists but may require community assistance. Switching between devices is seamless via Bluetooth.

Trade-offs

• ABS keycaps may show wear faster than higher-end materials.
• Num Lock functionality is limited to Windows OS only.
• RGB lighting reduces battery life significantly compared to backlight off mode.
• Relocated Delete key may require adjustment for users accustomed to standard layouts.
