i have the m84 (second mech i got) and it's a nice little keyboard it's the same exact size as a netbook. I have 2, one for my media pc cuz it's nice and small and the other i put for my fiancee cuz i changed her desk and the keyboard tray is smaller.
I have also modded a cherry brown keyboard and wow the g84 is a BIG difference, the switches aren't bad, better than membrane, about the same force as a cherry blue, but they feel mechanical mushy lol.
I was using it for a while until i needed my ergonomic option back, but once i tried cherry browns, the 84ml was ugh (but still better than the mushy membrane, and better than abs1).
idk if you'd want to game on it, it is ps2, i have no idea on nkro on it who knows, but it just doesn't feel like a keyboard for daily useage.
