I'm actually going off this keyboard... irregardless of the usb failure thing as that isn't bothering me much.
The keystroke reminds me too much of a Razer non-mech keyboard I bought 5-7 years ago... despite the actual pressure being low, it makes my fingers ache without much use.
Despite using it for a few weeks, I am still not used to the key layout... something which is very strange to me as I adjust quickly. I find myself mis-typing quite frequently as despite the subtle differences... it is quite different from the QPAD QT85 and other keyboards... this has a different layout and it's noticeable, even if it is only a couple of mm difference.
One thing I didn't like about the QPAD... is that you had to manually enable the back lighting every time you started the computer. The backlighting on this keyboard is the prettiest I have ever seen... but of course I look at the screen more than the keyboard
I'm going to buy a Corsair RGB to replace it and see how well I get on with that... otherwise I might end up going back to a QPAD again.
