Cfm Billet Valve Cover Breather Kit- 2002-2016 Mustang Gt

I came across the CFM billet valve cover breather that replaces the oil filler cap and from my understanding includes a one way check ball valve that's supposedly fully compatible with the factory PCV system and designed to stay completely closed during normal driving conditions while under vacuum, but will open under WOT/boosted conditions in order to relieve any unwanted crankcase pressure..

Anyway, I'd really appreciate any type of feedback from anyone who may be familiar with this breather kit or it's design concept..

In the meantime, thanks in advance...
