Well, when this question came up 5 years ago (see below) then I said I was really satisfied with my Razer Lycosa, that quite quickly changed though.
It had a number of
software problems.
And on top of that hardware problems, it's a known issue where a connector inside the keyboard makes poor contact that makes it not register key-presses.
Which reminds me of the Razer Habu gaming mouse I used to have, started double clicking on single clicks, defective micro switches of course, but also defective software because if connected via the same USB port the system would register keyboard presses when I moved the mouse while in the BIOS/DOS.
Maybe I should just give in and kill the damn thing like the mouse, sure felt better after that
Thing is I'm not convinced I wont hate what I replace it with, I looked at a boring yet expensive Logitech keyboard for business use some years ago, but of course they had to implement something in the firmware so you can't play with it, can't register key pressed of WASD in tandem, claiming that was a hardware issue when their gaming keyboards used the exact same hardware!
One thing is for sure though: I will never buy anything with the brand Razer printed anywhere near it!!!
