Good build quality. The Cooler Master MK730 has a plastic back frame that feels rather cheap, but the aluminum plate on top feels more premium. The entire keyboard is solid, doesn’t flex much, and even though it’s a bit on the heavier side, it’s still not too heavy to carry around. It comes with doubleshot ABS keycaps, and there are extra doubleshot PBT keycaps in the box, which are more stable. The detachable wrist rest is made from a plastic frame that feels a bit cheap, and there’s PU leather on top, giving it a more plushy feel. Also, there are rubber feet underneath the wrist rest to keep it from sliding around.
