ATTACK SHARK AJ139 G Pro Gaming Mouse 4K Polling - Lightweight

In this review the ATTACK SHARK AJ139 G Pro stands out as a lightweight, high-performance gaming mouse aimed at competitive players and heavy desktop users. The single biggest reason to buy is its combination of an advanced PAW3395 sensor and a 4000Hz report rate that delivers extremely responsive tracking and low latency, which clear casual lag and make fast flicks more consistent. The build prioritizes speed and comfort with a 65 g ultralight shell and an internal skeleton designed to keep hands relaxed during extended sessions.

Key Features

• 4000Hz report rate: Reduces input latency for faster on-screen response, helping precision in twitch-based games and rapid click sequences.
• PAW3395 sensor: Offers up to 26000 DPI, 650 IPS and 50G acceleration so minute hand movements are captured accurately for pixel-level aiming.
• 65 g ultralight design: The thin yet strong internal skeleton improves maneuverability and reduces fatigue during long play sessions.
• Long switch lifecycle: An improved 80-million click life and reduced double-click risk make primary buttons reliable for extended use.
• Wired and 2.4G modes: Offers low-latency wireless play or wired charging and play, giving flexibility for different setups.
• Customizable buttons and DPI: Six programmable buttons and six DPI levels let players tune the mouse to playstyle and software macros.

Who It's For

The AJ139 G Pro is best for competitive FPS and MOBA players who prioritize low latency and precise sensor performance, and for anyone who prefers a lightweight, responsive mouse for long sessions. The high DPI ceiling and fast report rate also appeal to content creators who need fine cursor control for editing.

Players who want a minimalist, ultra-premium ergonomic shape for large-palm comfort may want to test fit first, and users who require an included 4K receiver should note the 4K receiver is sold separately while a 1K receiver is included by default.
