I would note that I use the Razer Lycosa for a year now, and I'm on my third,
indeed a problem with the concept of the keyboard that the touchpad on the top right (and can control the multimedia app) sometimes hangs randomly some keys ... so here remarche, disconnect reconnect both sockets usb ... you imagine the embarrassment when in session or game must stop treating people either freeze waiting to die and slide under the desk leaving lots of swearing ...
short outside this manufacturing defect that specifies the I is not present on ALL keyboard but I had two in a row after an exchange store, the third seems to be good ...
at its appellation keyboard for gamer, I allow myself to put some downside, I'm rather versatile player pc, and I was quite interested in the macro keyboard functions, its rather affordable for key words gamer, and let's be honest aesthetic "kikoo" but we like all of us geeks ...
the final macro programming is complex and the supplied software is in English, very heavy ...
the quality of the finish is more than regrettable for a keyboard of this price, the keys get dirty very quickly and do not really hang ... the glossy design makes it all highly sensitive to fingerprints, and requires regular cleaning, the touch keys are gadget and we regret their too sensitive, they are active sometimes for no reason (a note that certain combinations of button changes the mode of backlight, rather géneant) and continue with the list of small defects but from 70 80 I think we can be demanding, both edges for tilting keyboard are in a super cheap plastic I broke into several just in normal use, the limit!
the finish is faster than a conventional keyboard or logitech microsoft, and his only assets are in my opinion the backlit keys, very convenient, and pleasant enough wrist rests,
in the end for the price, I recommend to go for a little higher if you want performance, and after either opt for Logitech G-series keyboards to say exotic and very flashy, see mechanical type keyboard or 7g blackwidow the same manufacturer to have a real typing speed and accuracy, and these keyboards are findable in stores or on amazon.
