After 6-7 months - my razer naga blackwidow ultimate took a poop, yes, it is broken my friends. After going through google I found tons of issues that people face. whenever I press YHN i get double letters. Tried few things to get it to work. Failed.
I remember few months ago while watching towelliee, he actually faced same problem - while playing, keyboard started to freak out, (ghost in the keyboard)_ lol
This is my second razer product, my mouse broke a year ago---
typing from old steelseries keyboard.
