Maybe I just got lucky with mine but I am very happy with it. The keys do fade I will give you that, but other than that its a very sturdy keyboard. I put some use on this puppy too, around 1 year of heavy use as well as the occasional(being modest when I say occasional) angry alt-f4 rage slams haha. I also love the look of this keyboard, very basic, just like my first keyboard when I was playing Prince of Persia on DOS lol.
It sucks to hear you have had that much trouble with your new toy, problems like that are never fun! I hope you have more luck with Corsair.
