Excellent type feeling and an impressive good quality overall. I was a bit reluctant to buy this model because of the red color, but im happy with it, has a very pleasant look.
No full documentation in the box, no documentation on Corsair site, quite a letdown especially on this particular keyboard that has a "mysterious" Bios switch with 5 positions. Also worth noting that Corsair has downloads on the support page for all K models (k30,40, 50, 60, 90) but nothing for the K70.
Volume control is badly thought/designed, the actual roll button is situated between two edges and that makes it harder than it should be to operate. On the Logitech 510, the whole button is operational not just the center part like on the K70.
I love the typing feel of this keyboard but its loud.
As for the non-documented switch near the place where the cable connects to the keyboard:
The switch selects between different poll timings (1,2,4,8) with 1 being the fastest and it has a "Bios" position for compatibility with older keyboards.
Depending on the polling mode selected, your operating system might not "like" the keyboard and the scroll lock led will start flashing. When this happens, the keyboard will still be operational with the exception of the windows-key disable button which wont do anything anymore. The solution to this is to turn off PC, move the switch to a diff. position and try again (sadly it wont work while the pc is on).
Disabling Logitech gaming software could also help with the compatibility issues.
One last thing: the so-called "reactive" mode (led lights on the key you press and fades away after) .....it might look cool in a very nerdy sort of way but the wear and tear it puts on the leds and the electronic components will shorten the life of your keyboard.
