...out of curiosity, i googled the world's most expensive keyboard

if the video not there anymore means someone at razer got to it

pressing keys repeatedly is still ok.
so far, with just simple tests like continuously hitting space followed by a letter, its slightly more accurate than the 7G at however fast i can go which on a good day can hit over 100wpm.

i guess when it says not really meant for gaming, its mostly due to the key clicks which you can also feel compared to the smoothness of the 7G cherry blacks.
but then it also doesnt really require much difference in force to press the keys between the two kbs.

btw, what custom switch? i dont see a mention of it anywhere.

well like razer already says in that site, with mech keys u do not need to bottom it out to activate the letter regardless if its blue or black.
but since there is no 'click' in the blacks etc, most users will bottom the whole key out as they want to be sure the key has activated...i also sometimes tend to do that with my 7G.
the 'click' btw is about halfway to the bottom.
guess thats why cherry blues are better for typing, so for those who need to mash alot of buttons, like RTS guys etc, it may benefit them more.
which i guess explains why it also has macro keys.
so to a FPS guy like me, all of it doesnt really matter
i still dont see a mention of the word 'custom' anywhere.
unless ur talking about them calling the cherry blues their own key which i agree is bs.
