So its been about 3 years that I have had the Lycosa, and it still runs like the first day. Realy nothing have changed, all the controls work perfectly, the backlighting works realy smoothly, and prety mutch everything is the same as the new one, exept for dirt pieces under the keys. So then why à 4 out of 5 you might ask. Well it is because the keyboard itself is a bit noisy. its not good if youa re in a bed room with someone who tries to sleep for example. I have no ther down point, it does work the way its expected to, as long as your Windows install the right drivers, not that I had any trouble with that, and that you take good car of it, by that I mean use it normaly, its gona last for ever. One other thing, I had had trouble with the fact that if you press the razer logo at the top right of the keyboard at the same time as the windows key, the windows key was disactivated. Not that I dont like the ability to do so, ut becasue I didn't know and accidently did it, and since it looks nothing like a button, I had to google it, but it was quickly fixed.
