had a few razer produts all broke before they should have for the money they cost.
my old £5 mouse lasted longer than my lachesis. (about 5years longer...)
there are better choices. razer are for them that want bells and whistles over usability.
there gaming matrix which they claim speeds up keyboard response actually reduces responsiveness on the rest of the key matrix as to make it appear the wasd and a few other keys are working quicker...
its a con. the keyboard is polling at 1000hz (1ms) regardless of how fast you press the keys.
then theres the lack of Nkroll over.
with no full key roll over there is no real effective anti ghosting. the method they choose can vary its results from 3-10 keys. which means on some key press combos the keyboard may or may not remember the last keys pressed.
das, ducky, q-pad, corsair,ttsports and logitech all have better offerings at less money.
