I've been using it for over a year. A nightmare thing, although initially I thought it would be value for money. The coating is worn out, some of the beeches are no longer visible. With backlighting, from which there is not much sense anyway, it looks just awful. The software is periodically buggy - the keyboard can reboot during the raid, it can start ating - so-so surprise. In general, the price for it is 500. Yes, it looks like the whole Razer is like that - the bottom with a claim to pro. With a fool, Chot bought himself both ears and a mouse, all at once. But the keyboard is still the most of course. Do not third the money for this in general, after a month you will dream of changing.
