Razer build quality is not that good.Saw my friend's G110 and it made me feel pretty bad over my purchase of the Lycosa.Quite a few keys have stopped working.Have RMA'ed it once and not feeling like doing it once more.Next time will buy a Logitech ^ series or a Roccat Isku.This one looks awesome.
BTW the Blackwidow Ultimate has backlight and not this one.
