It's an amazing keyboard. Nice and hefty. Weighs a little less than my M65-A, but that's expected considering it's also a bit smaller.
Anodizing looks very good, although the dark gray, when viewed in a certain light/direction, looks a bit greenish. Was unexpected, but I'm still very pleased with it.
It also sounds very nice (with 78g Zealios). Unsure of software or whatnot but the keymapping is done via
