I like this dustproof kit. All parts fit well and are sturdy. Apart from that, the PS4 Pro is designed to run on a constant flow of air. The foam vent covers bother me and I probably won't be using them. The rubber stoppers are a different story. They are solid and their use does not restrict airflow through the system. For any open port I would definitely recommend using these. As for the foam vents, I'll keep them for now, but my plan is to do regular maintenance to clean out the dust that the system needs on a regular basis
