The keys are wobbly because I'm used to from most notebook keyboards better. They also have very soon started to squeak uncomfortable (some might say "buzzing"), sounds really nasty. Is not extremely loud, but loud enough to bother me really. This squeaking noise bothers me really enormous and I have never experienced so with any other keyboard (and I really have a lot of keyboards at home). And then you can already see now handprints on the palm rest, which I think you also can not remove; So a bit of sweat should be as a palmrest actually already abkönnen (just because a black keyboard instantly heats up at the slightest sunlight). All this does not speak for a high quality materials and workmanship. I would prefer that the keyboard is another 20 euros more expensive and better for processed (and the keys do not squeak).
Last but not least: What have you thought of this is to build in a fixed switch to switch between F-keys and predefined functions, rather than a normal key, which can be short press (like a caps lock), I will never understand that's just a cramp and makes a quick change impossible if you like I usually uses function keys and then times will briefly change the volume using the keyboard.
