Product review (5 stars): Quality product
We have a black granite single bowl sink, that we love, but the ring that comes with disposals is always stainless finish and normally with its name engraved on it in huge letters.  We knew it would look awful, so bought a black flange and stopper set at our local big box store.  Our plumber installed it, it lasted about a month before flaking began.  The flaking continued, so we had our plumber put the original one on to try to like it.  Did not like it, found this one, had it installed and it has not shown any sign of flaking.  Very pleased with it and our sink looks great again!
