The mouse's body has a solid plastic shell and a symmetrical shape with textured plastic areas on both sides for added grip. This mouse is also noteworthy for including a range of accessories, including a charging cable, receivers, and adapters compatible with both USB-A and USB-C ports.

However, while it's somewhat lightweight, it isn't nearly as light as many FPS mice and isn't as easy to move quickly and accurately.
