Attack Shark X820Ultra Wireless 75% Mechanical Keyboard with Screen

In this review the Attack Shark X820Ultra is judged as a compact, feature-rich 75% mechanical keyboard aimed at gamers and power users who want flexible wireless options and a premium typing feel. The single biggest reason to buy is its combination of tri-mode connectivity and a hot-swappable layout that lets users switch switches without soldering while using Bluetooth 5.0, 2.4GHz wireless or USB-C wired modes. The included TFT screen and CNC volume knob add convenience, and the factory-lubed switches plus gasket mount and five-layer dampening deliver a notably refined sound and feel.

Key Features

• Tri-Mode Connectivity: Use Bluetooth 5.0, 2.4GHz wireless, or a USB-C cable to connect to multiple devices with stable, low-latency options for gaming or everyday work.
• Hot-Swappable Sockets: The pre-lubed linear gift switches and 3/5-pin compatible sockets let you personalize switch type and feel without soldering.
• Advanced Sound Dampening: A tuned 5-layer foam system with a gasket mount structure reduces ping and rattling for a deep, thocky acoustic profile.
• Custom TFT Screen and Knob: A programmable screen shows date, time and battery and the CNC knob controls volume and accesses RGB and connectivity menus.
• Premium Build and Keycaps: Textured PC plate, FR4 glass fiber PCB and PBT side-print keycaps provide consistent flex, durability and resistance to shine.
• Cloud Driver Support: Web-based software enables macro management, key remaps and custom RGB or GIF images without local installs.

Who It's For

The X820Ultra suits gamers who want a compact 75% layout with full N-Key rollover and flexible wireless options, and enthusiasts who value a refined typing sound thanks to the gasket mount and multi-layer dampening. Users who plan to experiment with switches will appreciate the hot-swappable 3/5-pin compatibility and factory-lubed linear gift switches for a smooth, buttery feel.

Those who should look elsewhere include buyers needing a full-size keyboard with numpad or users who require open-source local drivers rather than a cloud web driver. If you prefer a heavier, metal case or a different mount style, there are alternatives, but for compact wireless versatility and sound tuning the X820Ultra stands out.
