These are good quality all metal grills. I have used similar grills in the past. I addition to helping to increase case airflow, when paired with an appropriate fan they will also prevent larger dust particles from entering your system. The finish on these is a high gloss black paint. I would have preferred the finish to have been semi gloss or matte instead, so that they better match my case.
I'm pleased with my purchase and quick delivery. This is a great case mod.
