The HyperX Pulsefire FPS Pro comes in nearly the same windowless packaging as the previously reviewed Pulsefire Core. It's mainly red and white with some render images, technical specifications, disposal information, and marketing text. As for the insides, there's a thin cardboard casing that is covered in some transparent plastic on the front. The contents of the package are the mouse, a quick-start guide, and some brochures—no replacement mouse feet, unfortunately.
The Pulsefire FPS Pro is a big mouse for sure. It's a right-handed ergonomic mouse meant mostly for palm grippers. Robust and with a rather wide shell, similar to the Razer Mamba in dimensions and how it feels, it also resembles the look of the ASUS ROG Gladius II Wireless, but the FPS Pro is a bit wider and has a slightly lower profile.
Both sides of the mouse are narrow at the top and wide at the bottom. Even though with some slants and inward curves, the sides still are not perfect for a stable grip while the mouse is being picked up—at least for me. It just tries to slip out of the hand because of how the shell is shaped. Again, this is only an issue when you try to pick up the mouse. If you play on a higher sensitivity and don't lift the mouse up a lot, you're safe. Also, what doesn't work for me may work perfectly for you and vice versa.
Moving on to the measurements, the FPS Pro is 127.6 mm (5") long, which is a bit above average for gaming mice. The total width is 71.1 mm (2.8"), but depending on your grip style, the actual width at which it is gripped is approximately 60 mm (2.36"), so we're talking about a rather wide rodent. The total height is 41.9 mm (1.65"), and the hump is centered. With these dimensions, I would mainly recommend this mouse to palm grippers with hands that are at least 17–18 cm long. However, it can work with different grip styles and hand sizes outside of those parameters as well, as it's all a matter of personal preference. As for me, I couldn't claw grip it with my 18 cm long hands.
The whole right side is slanted a bit, and both main buttons feature some comfort grooves to help your fingers settle into a more relaxed position.
