I guess my keyboard isn't too dirty since i cleaned it a few months ago but i broke the W key from playing too much world of warships lol. But i replaced it with another key that i have no clue what it's for and never use it. I did leave the W key upside down on the keyboard to show it's broken. The M key also sticky sometimes and the space bar is a bit finicky sometimes but still works otherwise it's been a great keyboard over the years. I should probably stop being lazy and order a replacement key from corsair but i never gotten to it.
