Hello!
So I have the K95 vengeance mx brown 2 years now, I have been struggling with the double click, I RMA it and got a new one about a year ago and still had the same problem with different other letters.
I finally solved the problem!! :laughing:
Just remove the key cap push the switch and put 2~3 drops of mineral oil or liquid silicon(I used WD40 spray) and it will never double type again!
