The G-Wolves HSK Pro 4K is an extremely lightweight wireless gaming mouse that's part of G-Wolves' HSK Pro lineup of gaming mice. It has a plastic shell with honeycomb-shaped cutouts that help decrease its overall weight. It features an unconventional shape that's specifically designed for use with a fingertip grip. It also features PixArt's PAW3395 sensor and supports a maximum polling rate of 4000Hz out of the box or 8000Hz with the additional purchase of the G-Wolves 8k receiver.
Our Verdict
The G-Wolves HSK Pro 4K is an okay mouse for work, but it's not designed for this use. It's extremely small and only suitable for use with a fingertip grip, which might be uncomfortable for long periods. You can connect to it wirelessly using its included 2.4 GHz USB receiver, but it doesn't support Bluetooth or multi-device pairing. Its scroll wheel also lacks useful features like a free scrolling mode and L/R tilt inputs.

The G-Wolves HSK Pro 4K is an outstanding mouse for FPS gaming. It's incredibly lightweight, making it nearly effortless to move accurately and precisely. It also has excellent performance, with remarkably low click latency and an accurate and precise sensor, resulting in a very responsive gaming experience. However, its unconventional shape is only suitable for a fingertip grip, so this mouse is not a good option if you use a claw or palm grip.
- Extremely lightweight.
Maximum wireless polling rate of 4000Hz or 8000Hz with the purchase of the separate 8k receiver.
- Incredibly low and consistent click latency performance.
- Excellent all-around sensor performance.
- Small size and shape only suitable for a fingertip grip.
Unusual 8000Hz implementation issues using the separately purchased 8k receiver.
Despite not being designed for this use, the G-Wolves HSK Pro 4K is good for MMO gaming. It has good build quality and excellent click latency and sensor performance. While you can remap its buttons using the customization software, it doesn't have nearly as many as dedicated MMO mice. Also, its unusual shape is only suitable for a fingertip grip, which might be uncomfortable for long gaming sessions.

Unusual 8000Hz implementation issues using the separately purchased 8k receiver.
The G-Wolves HSK Pro 4K has superb raw performance. It has outstanding click latency and an excellent sensor that's accurate and precise. It also supports a maximum polling rate of 4000Hz out of the box, delivering slightly more consistent performance over a standard 1000Hz polling rate. Following a post-launch firmware update, this mouse now also supports a maximum polling rate of 8000Hz with the separate purchase of the G-Wolves 8k receiver. Unfortunately, our Click Latency and Sensor Latency results suggest there may be an unknown issue with the implementation of 8k polling, resulting in worse performance.

Differences Between Sizes And Variants
The G-Wolves HSK Pro 4K has several color variants: Grey+Red, Grey+Green, Pink, Black Pearl, Ruby Red, and two variants each of Sapphire Blue and Turquoise. We bought and tested the Grey+Green variant. G-Wolves also sells the HSK Pro ACE, which is virtually the same as the HSK Pro 4K but supports a lower maximum polling rate of 1000Hz.

Popular Mouse Comparisons
The G-Wolves HSK Pro 4K is an ultra-lightweight wireless gaming mouse that's part of G-Wolves' HSK Pro lineup of mice. It has a very small shape that's designed to be used specifically with a fingertip grip type. It's about half the size of an average gaming mouse, meaning it's significantly lighter than most gaming mice, but it doesn't have the flexibility that others have since most are designed to suit a range of hand sizes and grip types. The Zaunkoenig M2K is another fingertip-only mouse, but it's wired and has been discontinued. The Keychron M4 is a new lightweight wireless gaming mouse that features a similar fingertip-only shape.

The Finalmouse UltralightX and the G-Wolves HSK Pro 4K are high-performance, lightweight, wireless gaming mice. The G-Wolves is lighter but significantly smaller and only suitable for a fingertip grip. The Finalmouse has a more conventional symmetrical shape, so it's also suitable for claw and palm grip types. The two mice perform similarly, but the Finalmouse has better sensor latency performance.
The G-Wolves HSK Pro 4K and the Zaunkoenig M2K are high-performance, lightweight gaming mice. They are both extremely small mice designed to be used with a fingertip grip only. The Zaunkoenig M2K is a wired-only model, and it lacks side buttons. It's also made of carbon fiber and has a maximum native polling rate of 8000Hz. On the other hand, the G-Wolves is wireless and supports a maximum native polling rate of 4000Hz (or 8000Hz with a separately purchased G-Wolves 8k receiver). It's also not as well made as the Zaunkoenig, and it's made of plastic instead of carbon fiber.
