Attack Shark X820Ultra 75% Wireless Mechanical Keyboard - Screen

In this review we look at the Attack Shark X820Ultra, a 75% wireless mechanical keyboard designed for gamers and heavy typists who want flexible connectivity and a premium typing experience. The bottom line: it is best for users who want a compact layout with tri-mode wireless, a programmable TFT screen and a tactile, thocky acoustic profile thanks to a multi-layer damping system. The X820Ultra stands out because it combines hot-swappable sockets with a gasket mount and factory-lubed switches so customization and a refined sound are possible without opening the case.

Key Features

• Tri-Mode Connectivity: Switch easily between Bluetooth 5.0, 2.4GHz wireless and wired USB-C to use the keyboard with phones, tablets and PCs.
• Hot Swappable Sockets: The pre-lubed linear shark switches and 3/5-pin compatibility let you change switch feel without soldering.
• Advanced 5-Layer Sound Dampening: A PORON sandwich plus multiple foam layers and a gasket mount deliver a deep, thocky acoustic signature and minimal case ping.
• Custom TFT Screen and Knob: The programmable screen displays date, time and battery, and the CNC knob controls volume and menu interaction.
• Robust Battery and Cloud Driver: A 4000mAh battery supports long wireless sessions and the web-based cloud driver handles macros, remaps and RGB without installs.
• Durable Keycaps and Rollover: PBT keycaps resist shine and full N-key rollover ensures every simultaneous press registers during gaming.

Who It's For

The X820Ultra suits compact keyboard fans who want a premium build and sonic refinement; mechanical keyboard hobbyists will appreciate the hot-swap sockets and gasket mount for tuning sound and feel. Gamers who need reliable wireless performance and a dedicated knob or those who like an integrated screen for quick status checks will find this a strong fit.

Those who want a full-size layout with a numpad or users who prefer optical switches over linear hot-lubed mechanical switches should look elsewhere. Also, if you require an offline, installable driver rather than a cloud-based web driver, consider alternatives that offer local configuration tools.

Pros & Cons

Pros
