Got mine yesterday. All in all I'm happy for the money it cost. Yes the keys wobble a bit and yes the case won't sit flat on my desk. But I like the feel of the green Alps, and their ridiculous noise. Linear Caps Lock and Num Lock is puzzling, and actually pretty annoying since I have Caps remapped to something that I use constantly. Nevertheless it's a fun board to have around for when I'm feeling like being loud.
One puzzling thing is that when I plug it into my Windows machine via a USB extension cable, I see its lights flash and hear the telltale "byeow byeow" that tells me Windows has found new hardware, but typing produces no output. If I plug it into a USB port directly, all is well. The keyboard works fine through an extension cable on my Linux machine at work, and it even works fine on my machine at home before Windows loads (e.g., changing BIOS settings and using my boot menu).
Any ideas?
