I bought myself a nighthawk x8, here's my story on why you should not do it.
After 2 years of moderate use it stopped working, from day to night, with no apparent reason. Apparently something went wrong in the firmware and fucked up the keyboard so badly it is now completely unusable.
Here's how I managed to fuck up the firwmare. Think I was messing around and got (rightly) punished? Not quite. What I did was: turn off computer; plug it off (after it was well shut down; not midway or something like that); plug back in after 1 day or so; turn on computer.
Result: keyboard only recognized as "generic usb hub", and not usable anymore.
The only thing I can do now is order that 40$ piece of equipment from them, or send the keyboard to them and let them repair it (at my cost, since warranty it's only 1 year; at this point for a good reason from their part I suppose).
Here's their response:
"Based on the information, we would guess the keyboard's firmware has crashed, in order to refresh the firmware will require firmware re-write device"
And, when I asked how the fuck a 130$ piece of equipment can get broken so badly just by turning of and on my computer:
"There are many factors could cause the damage on keyboard or firmware crash, such as sudden electrical spike."
Which is complete bullshit: I don't call turning the pc on a "sudden electrical spike". And if it can get damaged so easily, well, gg build quality I'd say.
So yeah, I advise you don't buy any of their keyboard, they seem to have really shitty quality if they can get broken by something like this. Save your money and choose a better company.
Note to self: If warranty is only 1 year it means the build is shit. This probably for every piece of technology out there.
