I have read a couple of reviews of the Corsair K70. In short:
- More silent than regular Cherry MX Red.
- No complaints about being stiff or scratchy ...
- The keycaps are wider on the top because the switches are wider on the top than Cherry MX.
- Oh my God, the Light Bleed! If you have only one key lit, it looks like two keys in every direction are also lit.
BTW. According to Rama.Works' blog they are smoother on off-centre key presses than Kailh "Choc" low-profile switches.
I actually wonder if Corsair bought the right again so in which case everyone else have to wait a year till they can use it.
Cooler Master also has keyboards with these switches to be released soon.
Sigh. No chance of low profile @ ~35g? That'd be my freaking dream.
We'll just have to see if we could open them up and replace the springs with something. I'm guessing that the spring is different from regular Cherry MX — but that problem could be overcome, like there are now third-party springs for Cherry MX.
