SPECIFICATIONS

FREEWOLF x ATTACK SHARK M75 (often branded simply as Attack Shark M75) — a tri-mode 75% wireless “membrane” (mechanical-feel) gaming keyboard featuring a knob and OLED display, gradient PBT keycaps, and rainbow backlighting:

🔧 Design & Build

• Form Factor: Compact 75% layout (~81 keys) retains essential function, arrow, and number row keys while freeing up desk space 

• Materials & Keycaps: Side-printed, spherical gradient PBT keycaps (pink/cream/blue options). These resist fading and oil stains, offering a durable, ergonomic typing feel 

• OLED Smart Display: A small screen shows battery level, connectivity mode (wired/2.4 GHz/Bluetooth), device status, and volume level 

📡 Connectivity & Control

• Triple-Mode: Switch seamlessly between USB‑C wired, 2.4 GHz wireless (via dongle), and Bluetooth 5.x. Supported pairing with up to three Bluetooth devices 

• Rotary Knob: Located top‑right, the knob adjusts volume or backlight brightness, and pressing it switches connectivity modes 

✨ Lighting & Key Switches

• Backlighting: Rainbow LED with ~18–27 effects including static, breathing, and dynamic modes. LEDs are south-facing under the keys, so shine-through is limited unless keycaps are modified 

• Switch Feel: Despite being marketed as “membrane mechanical feel,” most units use linear “white” or “viridian” custom switches with gasket-mounted construction and PORON padding—delivering a cushioned, smooth, quiet typing experience resembling a mechanical feel 

🔋 Battery & Usage

• Battery Capacity: ~2000 mAh battery (some sources claim 3750–7000 mAh, but actual tests show modest life) 

• Real-world Life: Users report around 4–5 days of use per full charge—particularly limited by OLED usage. Charging benefits from USB‑C and quick fill time, but battery longevity is average

📝 Feature Summary

The Attack Shark M75 offers a striking package for budget gamers and productivity users—featuring a knob, OLED, and premium gradient PBT caps in a space-saving form. However, firmware concerns, modest battery life, and limited RGB shine-through may drive heavier users toward more polished alternatives.
