I've been hearing quite a bit about the velocifire keyboards (30 USD for TKL, standard layout, doubleshot abs keycaps, single color backlighting) but the main thing that is kinda turning me away is the switches, zorro brown. I've heard from reviews that theyre pretty grainy and have a weak tactile bump. Is there anyone here that have used zorro switches for a longer period of time? If so, how are they working out in the long run, change in key feel at all? Thanks!
