In the beginning everything works perfectly and we see over time that drivers are actually a Windows service, so the service can crashes and of course often happens.
When this happens of course is that all there is or you know what you can do with the screen becomes zero, nothing of work.
In order to make the new work must be electrically disconnect the keyboard, or unplug the use or reboot the machine to enable the Windows service to run this or most often for me it's is three. Or when changing to one or more devices, option of teamspeak it can also crash the system keyboard.
expeample most concrete I have an output jack for headphones, but once it removed the audio peripheral s' therefore moving on out of my speakers and AC AC is precisely crash every second keyboard of the service.
In line forums I met enormously people who have similar problems but without results. Indeed it's the developers of the keyboard (madctatz) that its problem. I contacted several times the Madcatz sav and after some time I got send wandered.
So actually for the price the keyboard is not worth the trouble. C is true that it is of very good quality materials but the rest is very disappointing.
I specified that my use is purment gaming, several hours a day for 1 year and this, I think I asser step back to allow me this comment.
