Surface
As for the surface coating, Fnatic didn't go cheapskate; they went with an oleophobic surface treatment on the top panel, or at least that's what they claim it to be. In reality, this surface loves to collect fingerprints and dead skin cells. However, it is very grippy and has a lot of friction, yet remains relatively smooth to the touch. The narrow middle panel surrounding the scroll wheel and CPI buttons has the same texture. The scroll wheel is rubberized and line-textured, which should prevent any accidental slips while scrolling.
As for the side panels, they are quite fantastic to touch. They are both treated with some sort of rubberization and lightly textured with inward dots. These panels are very smooth but quite grippy. They unfortunately have less friction than the top part of the mouse, but should still provide enough grip for everyone. I have rather sweaty hands and had absolutely no slips even when repositioning after bigger flicks, and I play at a very low sensitivity.
Build Quality
Fortunately, the Flick 2 has great build quality. I could not make the mouse creak or squeak even when I pressed down on the shell really hard. There is absolutely no rattling present, either. My only concern is a bit of unnecessary travel on the main buttons, but more on that a bit later.
Weight
The Flick 2 weighs about 99 grams (3.49 oz) with a few centimeters of cable (the manufacturer claims it to be 93 grams, but that's entirely without the cable, and you always move the first few centimeters of the cable along with the mouse. It's a fairly decent weight for a mouse of these dimensions, but I think it could be a littler lighter. Generally, a lighter tracking device is better for your wrists in the long run. Thankfully, the weight is evenly distributed and well balanced.
