A deeper stroke than a LapTop; very... solid, very comfortable for me.
Does it feel like it has sturdy construction?
Who's to say what that means. The base body's thin and looks like it could be damaged were it dropped on its edge from a height, but it FEELS solid. I've had zero issues with it in 6 months of daily use, including the occasional drops from table to carpet.
Does the paint on the keys rub off leaving you with light smudges or are the keys truly high quality where the plastic itself is either black or transparent?
The keys are not top-etched or, to my examination, painted on the top-side. I'm guessing they are trans-parent/-lucent with black on the underside and a white diffusing on the symbols (illuminated area). Those symbols are crisp and appropriately sized/readable.
I've kept my eye on this keyboard over the years and it's a candidate to replace my current keyboard.
At this price I'm thinking of buying my third! Different folks like varying keyboard strokes; this is about ideal for me -- -much- preferred over the LapTop style.
Note: I've never used the super-functions keys [FNCTN + F2 = "email", FNCTN + F11 = "pause/play", etc.] so I don't know if they work, but I've no reason to doubt they do.
PS: re' "noise" -- It's quieter than olde mechanical keyboards, but still has a comforting "slap" as I type on it, perhaps more on the space key than on the letters.
