My 6gv2 arrived last week ^.^ I think it's great value for the money, the keyboard is definitely very heavy and the rubbers under it make it very stable too. I haven't tested the nkro features but so far i had no troubles. The keys are quite hard to press (they use cherry blacks) which, again, is really great for gaming (for me anyway, that way i don't press any keys by accident).
If i had to criticize it i'd say that the letters on the key caps tend to fade quite fast (at least the keys i use for gaming). I don't mind much but some may. Also i'm having second thoughts about the type of switch: as i said, for gaming it's great for me, but i have also some more serious activities on my computer, and i'm wondering if i shouldn't have chosen a keyboard with cherry mx browns instead. That being said, it's all rather new, this is my first mechanical keyboard and i really like the change from the
microsoft comfort curve keyboard i had. I guess i'll give it a few weeks to get used to new keys and layout. Still, the
zowie celeritas looks quite interesting too ^.^
Time will tell (and budget too of course...).
