The Gravastar Mercury X Pro 8K is shaped like an alien beetle, featuring an extremely unique look with a highly distinctive design style🪲. Its shell adopts a magnesium-aluminum alloy skeleton structure. Though it is not a small-sized mouse, it weighs only 49 grams, making it quite lightweight. The shell has a special perforation layout, with an internal dust cover resembling an insect’s abdomen. When the lights light up, the mouse looks just like a firefly.✨
In my opinion, the overall shape of the Mercury X Pro 8K is quite similar to the Logitech G PRO X SUPERLIGHT(124 mm × 63.5 mm × 40.5 mm). Both have well-proportioned three-dimensional curves and lateral width. The side walls of the mouse are also perforated, with the holes tilted toward the hand. When gripping the mouse, my thumb and ring finger will feel a slight discomfort. However, anti-slip grips are included among the accessories. If you dislike touching the perforated shell directly with your fingers, you can choose to attach the anti-slip grips.
I once shook the mouse vigorously and squeezed it hard, yet there was no rattling or loose parts at all, which proves that the mouse is well-built and sturdy.
The receiver adopts the same alien insect-style design. Unfortunately, the RGB lighting effects of the receiver cannot be modified or set separately, so its light effects cannot match those of the mouse.
The tactile feel of mouse buttons is something I always pay close attention to, and the left and right buttons of the Mercury X Pro 8K perform excellently. Equipped with Omron white dot switches, they deliver a very comfortable pressing experience with moderate actuation force and clear rebound. There is no sluggishness or discontinuity during consecutive clicks. The side buttons require lighter pressing force and feel more comfortable than the main buttons; honestly, I really love the tactile feedback of the side buttons. Meanwhile, the scroll wheel rolls smoothly, offering effortless rotation while retaining clear tactile feedback.
The Mercury X Pro 8K is fitted with a PAW3950 sensor and a Nordic nRF52833 main controller. It supports three connection modes: Wireless, Bluetooth and Wired. It can reach a maximum 8KHz polling rate, and all settings can be adjusted via a web page without downloading dedicated configuration software. It is fully capable of handling daily office work and all gaming scenarios. The mouse comes with a dedicated 8K receiver, which uses the same alien insect-style design. Regrettably, the receiver’s RGB lighting effects cannot be adjusted individually, so its light patterns cannot align with the mouse’s.
Lastly, I have a few optimization suggestions for Gravastar: the rear section of the mouse base could be improved properly. Two protrusions here may undermine stability when lifting and placing the mouse back down. If the mouse lands unevenly or if the user tends to rest their wrist down first, these protrusions will scrape against the mouse pad. The problem becomes more obvious on soft or thick cloth mouse pads, where the bumps sink into the fabric. This could lead to critical errors during intense FPS matches.🤔
These are all my thoughts on the Gravastar Mercury X Pro 8K. I believe this mouse is more suitable for players with hand lengths of 18.5 cm and above. It delivers powerful all-round performance, and its bizarre silhouette makes it ideal as a mouse for both office work and gaming, as well as a highly unique desktop ornament.
