Has M30 Scroll Problem Been Fixed?

I want another Raptor M30 but need to know if the bouncy scroll wheel issue (scrolling down will sometimes bounce up as if I scrolled up one tick) has been resolved before buying another one. The one I have now does it sometimes but it is very rare, whereas the one I had before this one (had to RMA that thing) was so bad I couldn't even use it.



If it has been resolved what is the revision number so I can make sure I get one that works correctly?
