Well, I have only been using this Rosewill RK-9000RE as my daily driver at work for a few months, and today the Enter key gives out. It's probably a bad solder joint, and I'm sure I could fix it pretty easily. But I'm debating whether to actually fix the thing, or just to harvest the switches from it. I know they're cheap, but TBH I expected more from a $64 keyboard made by Costar.
Using this Rosewill was sort of an experiment, anyway, to see how long a cheap mechanical would last, compared to my Filcos, Pokers, etc.
