Crankcase air breather

Is anyone running a crankcase air breather? The one u out on your valve cover in place of the oil cap? If so does it do anything really? And also does it make a mess in the bay?

I have been for probably 20k or so miles with no issues. The filter gets dirty of course but it doesn't get in your engine bay. I put it on the same time as my catch can and my smoking issue went away so I can't really say for sure but it's worth it to me.
