i own 2 valves myself , the fmj fire and the dark grey grey valve. 
 
For the dark grey/grey valve , the icon peels off too easily. 
 
For the fmj/fire valve , it really sucks . 
I used it for the first time since coming back from the oakley service center and the most of frame paint came off .! 
 
of course it's cheap , hence the cheapo quality.
