Prawn here with a look at the Gravastar Mercury V75 Pro, a 75% layout keyboard that's packed full of features. It includes Hall Effect switches, 5 layers of sound dampening foam, multi-zone RGB lighting and impressive specs too. Despite its alien appearance, this keyboard boasts some very decent gaming specs including:
8000Hz polling rate and 256kHZ key scanning
Adjustable actuation switches (0.1mm to 3.5mm)
Rapid Trigger settings and SOCD/Last Keystroke Prioritisation
And more besides
In this video I'm showing you all the different things that are interesting about this keyboard and what I like and don't like.

Full specs:
True 8kHz Polling Rate: Boasts an 8000Hz USB polling rate paired with 256kHz key-position scanning, reducing latency to a near-instantaneous 0.125ms.
GravaStar UFO - Hall Effect Gaming Switches: Engineered for 0.005mm precision with adjustable trigger depth (0.1mm–3.5mm) to eliminate lag and enhance control.
Adjustable Actuation Point: Customizable trigger depth (0.1mm increments, 0.1mm–3.5mm) to suit playstyles—shallow for fast combos, deep for precise inputs.
Dynamic Rapid Trigger: Dynamically adjusts activation/deactivation points based on key travel (not preset limits), enabling fluid rapid-fire key repeats.
Last Keystroke Prioritization (LKP) + Snap Click: Prioritizes the last-pressed key for smooth directional changes; resolves simultaneous presses by favoring deeper inputs.
Rapid Trigger Mode: Eliminates key "stiction" with instant reset on upward travel, enabling faster re-presses and input switching.
Semi-Aluminum Construction: Combines a sturdy aluminum frame (for durability) with a premium plastic base (lightweight, modern desk aesthetic).
Hot-Swappable Design: Allows switch swapping (no soldering) with magnetic Hall Effect switches; compatible with select TTC and Gateron models.
5-Layer Acoustic Foam: Minimizes keystroke vibrations for crisper sound and smoother typing feel.
16 Modes, Dual Systems, Multi-Zone RGB Lighting: Customizable 16 dynamic modes, dual-zone control (keys + ambient side lights), and adjustable hue/saturation/brightness.
