Steelseries is so... 2000 and late?
I think Reg ought to demo a Wooting 2 Lekker or HE edition (when available). It will utterly dominate the Apex Pro in every way except maybe less OLED. Software is mature, everything just works but has ridiculous amounts of customization available. MUCH higher sensitivity range (0.1mm to 4mm) with full analog translation over the entire keystroke if needed. Can also fire multi actions based on key travel.
