It has outstanding build quality. It has a solid aluminum case covered by a plastic top cover that feels nice and exhibits almost no flex. The doubleshot PBT keycaps have a slight wobble to them, and there's a small rattle from the spacebar stabilizer, but otherwise, everything feels sturdy. There are two rubber feet on the bottom that are surprisingly great at preventing it from sliding, and the plastic incline feet also hold it in place very well, although they feel cheap compared to the rest of the keyboard.
