Redragon K688WGL-RGB-PRO 98-Key Gasket Wireless Mechanical Keyboard – Tri-Mode USB-C / 2.4 GHz / Bluetooth, Hot-Swap, Rotary Knob, MDA Profile RGB

The Redragon K688WGL-RGB-PRO is a high-end 98-key (96 % style) wireless mechanical keyboard aimed at gamers, professionals, and keyboard enthusiasts who want performance, aesthetics, and flexibility. With tri-mode connectivity, hot-swappable switches, a gasket-mounted build, and a rotary knob for quick controls, it offers a well-rounded feature set for a premium typing and gaming experience.

Design & Layout

The keyboard uses a compact 98-key layout (often called 96% plus extra features) that retains most keys you'd find on a full-size board while minimizing width. This gives you arrow keys, function row, and a numpad area-like cluster without making it bulky. 

To reduce acoustic resonance and deliver a richer typing feel, Redragon designed it with a gasket-mounted architecture combined with five layers of sound-damping materials. This structure absorbs cavity echoes, reduces ping, and softens the feel of key bottom-out. 

Connectivity Modes

One of the major strengths of this board is its tri-mode connectivity:

• USB-C wired mode for zero-lag, powered operation

• 2.4 GHz wireless, for near-wired responsiveness

• Bluetooth, for flexible multi-device pairing

The wireless modes support a range of about 10 meters per the manufacturer specs. 

You can switch modes depending on your use case (desktop vs portable) without needing multiple keyboards.

Switches & Hot-Swap Capability

The keyboard comes with pre-lubed linear switches (often branded “Cream / Longyin”) for smooth and relatively quiet operation. 

It also supports hot-swappable sockets (both 3-pin and 5-pin), enabling you to change switches easily without soldering. 

This flexibility is ideal for users who like to mod or upgrade over time.

Knob & Controls

A built-in rotary knob gives quick access to volume control, RGB adjustment, and mute functionality. Short press / twist / long press combos let you cycle lighting modes or make quick adjustments without software. 

Multimedia and FN keys are layered to retain functionality without extra bulk. Keys support anti-ghosting for full 98-key rollover. 

RGB & Lighting

The K688WGL supports 16.8 million RGB colors, multiple lighting modes (16 modes listed by manufacturer), and customizable effects. 

Lighting is viewable through keycaps and board accents, enhanced by the design to showcase internal lighting.

Practical Use & Applications

• Gaming: Use wired or 2.4 GHz mode for minimal latency

• Productivity: Compact layout saves desk space while retaining essential keys

• Multi-device use: Bluetooth mode allows switching between PC, tablet, or phone

• Modding / Enthusiasts: Hot-swap support + gasket structure + choice of switches

• Quiet environments: Damped structure helps reduce noise

Limitations & Considerations

• Wireless latency may still lag behind wired for ultra-competitive play

• Battery life (not explicitly stated in source) will vary with brightness and usage

• The small package dimensions / weight from some listings seem unrealistic — actual shipping box will be larger

• Full software / driver support might only work in wired or 2.4 GHz modes

• Compact layout requires FN-layer shortcuts for some keys
