previously indestructible part

Property unfortunately so defused some keyboards, less by liquids, mostly by dirt inevitably settles over time in the crevices and holes and the keys can be stiff. That's with this keyboard from Logitech history. The keys have a nice response, almost a bit much and too little quieter they could be, but that's just my impression and you can not have everything at once. I do not know how it will look in the future, I'm not the great writer, but the dirt remains in the dishwater and the keys smoothly, nice idea. My conclusion, HIGHLY RECOMMENDED !!!
