Surface and Materials
The front, top, and non-rubberized parts of the side panels are coated with a metallic, extremely subtle beige-colored semi-matte paint that is pleasant to the touch and generally provides enough grip for most people. This is the same sort of paint as on the previously reviewed Cougar Minos X5, Tt Ventus X or ASUS ROG Gladius II variants, and others. It doesn't collect fingerprints too easily and is easy to clean—I've got to say it's definitely one of my favorite surface coatings.
Both side grips are rubberized and have a diamond-plate texture that is mainly used on steel or aluminium tiles to prevent slipping. This works relatively well; it's nice and grippy with dry or slightly moist hands, but gets noticeably more slippery when wet.
The side buttons are glossy, the CPI button features the same surface coating as the top shell, and the scroll wheel has a rubberized outer layer.
Build Quality
Build quality is very solid on the FPS Pro. I could only make it emit some very quiet creaking sounds when I pressed on the shell with great force from the sides, which would never happen in regular use. The whole mouse is very well put together. I could find no errors whatsoever. Both mouse feet are aligned perfectly in their slots, and the buttons don't seem to have any play or unnecessary travel either.
Weight
The Pulsefire FPS Pro weighs about 99 grams on my scale with a few centimeters of cable. This means it's average in terms of weight, but feels rather light for its size compared to most of its competition with similar dimensions. Generally, a light mouse is better for your wrists in the long run than a heavy one. As for the balance, it's very well done—the weight is evenly distributed across the whole body.
