Mechanical keyboards are an entire hobby these days: you can go as deeply down the rabbit hole as you want to with every component, all the way to building your own from scratch from the component parts. That's a fun hobby and a lot of folks enjoy it, but just like building a gaming PC, sometimes you want a reasonable solution that comes right out of the box ready to work at a high level of quality. That's what NZXT is offering here with the Function 2.The design of the model I tested is a very traditional layout with separated cursor control keys and numeric keypad, which is my personal preference. The keys are pushed right to the edge of the board, keeping desk space used to a minimum. A wrist rest that's optional is provided; I liked using it for my own preferences. It connects via magnets to the front and has a whopping ten feet on the bottom to keep it from sliding - while the two parts never permanently connect, I never had problems with it moving around. It's a neat design.The keyswitches here are high quality optical switches, which means there are no electronics in the switch itself - there's a little plunger that pushes down to break a beam of light between an emitter and a sensor. That lets the keboard offer customizability for the point where the keys activate, so you can make it more or less sensitive depending on your preferences. The switches are marketed as NZXT branded, but what I received was made by Gateron - that's a good thing, as they're a well respected optical switch brand. It also means you can swap in your own separate Gateron switches; a switch puller is included and they even give you four each of two replacement switches if you want to increase or decrease force for arrow or WASD keys. You can always buy more.This is billed as 'quiet', but if you're sensitive to noise, it's definitely not the keyboard for you out of the box; quietER is probably a better description. It's nowhere near as clacky as many traditional keyboards are, but it's way louder and more intrusive than, say, a Microsoft Natural Keyboard or any laptop. If you're using this in an office, you're going to annoy your neighbors. Maybe that's your goal. The noise is entirely from the plungers bottoming out in the Gateron switches, no rattle from the case or anything, so if you can get your hands on the 'silent' versions with dampers, that would make this perfection - they seem really rare/unobtainable though.I found the typing experience on this to be pleasant, with very little force required. On the most sensitive setting, I did get the occasional accidental activation from resting my hands on the keys, so some tuning is probably reqired for my habits and preferences there. I felt this was definitely more of a gaming keyboard than an office one for that reason - your gaming activations will happen quickly and reliably, but you might get a few extra unwanted keystrokes in an office environment. It's also not an ergonomic layout, which is what I personally prefer, so much better for suited for gaming when your other hand is going to be on the mouse anyway.Finally, yes, it has RGB lights. They're pleasantly glowy but not overly bright, since they need to filter through the keycaps. (The keycaps are high quality, by the way, with a doubleshot effect for the light lenses.) There's a utility that helps you customize them, and once the customization is done the keyboard remembers your preferences. Other cool features include a volume knob that works very well and side shortcut buttons with no risk of accidental activation.This is a great gaming keyboard that includes a lot of the latest trends that I think will please a lot of people. If you're interested in dabbling in becoming a DIY keyboard hobbyist, it's not a bad canvas to start with and then swap out the underlying keyswitches if you want to explore that route. For office typists, I do think something else might be a better fit, though - this is definitely a purpose built gaming keyboard.
