Hello everyone, I am a seasoned gamer who enjoys playing games like无畏契约 and CS:GO. As a dedicated gamer, I have very strict requirements for my peripherals, especially mice. FPS games place a high emphasis on feel, and after using the Logitech G Pro 1st Gen for two years, followed by the Razer Viper V3 Pro for another two years, I was in need of a new mouse. With a budget of around 300 yuan, and considering the excessive playtime in the game 无畏契约, I needed a lightweight, high-refresh-rate mouse. After much consideration, I finally decided on the RK K3 black edition, which I affectionately call the “Black Knight.” After using it for over a month, I would like to share my experience and why this mouse is perfect for gamers.

Introduction to the RK K3 Mouse
Upon receiving the package, I was impressed by the cool design of the mouse packaging. The black and orange color scheme and the pull-out structure exuded an esports vibe. Inside the box, I found a variety of accessories:
- Mouse Body: I chose the black “Black Knight” edition, with a matte texture and side waist design, which directly boosts the aesthetics. It feels smooth and non-slip to the touch.
- Parachute Rope Data Cable: With a Type-C interface, it is soft like noodles and can be used as a wired mouse. It can also be charged while playing.
- 8K Receiver: This is the core of the esports experience, allowing for a 8000Hz report rate in wireless mode with extremely low latency.
- Foot Pad Instructions: The foot pad needs to be applied manually. Aligning it correctly is crucial for smooth sliding.

The mouse measures 119.62 x 62.8 x 38.3 mm, which is suitable for medium to large-handed users. After applying the foot pad, the weight is 47.3g, feeling as light as a feather in the hand, which completely relieves the wrist during rapid movements.
Design and Build Quality
The RK K3 black edition has a sleek and modern design. The matte black finish gives it a premium look, and the side waist design provides a comfortable grip. The mouse is lightweight, which is a significant advantage for long gaming sessions. The build quality is excellent, with no creaks or loose parts.
Features and Performance
The RK K3 is equipped with the PAW3950 dual 8K sensor, which is a significant upgrade. This sensor provides exceptional tracking accuracy and responsiveness, making it ideal for FPS games. The mouse also features customizable buttons, allowing for personalized settings to suit your playstyle.
The mouse’s performance is top-notch. It offers precise tracking and minimal cursor drift, ensuring accurate aiming and movement. The high-refresh rate sensor ensures that your movements are captured without lag, providing a smooth and responsive gaming experience.
Wireless and Wired Modes
The RK K3 supports both wireless and wired modes, providing flexibility for different gaming scenarios. In wireless mode, the 8000Hz report rate ensures minimal latency, while the 1.8m USB cable provides a stable connection in wired mode.
The wireless mode is particularly impressive. The mouse is lightweight and offers a seamless wireless experience with minimal interference. The battery life is also impressive, providing up to 60 hours of playtime on a single charge.
Conclusion
