We purchased this undermount sink to install with new quartz countertops  in late October, 2018.  The sink looks beautiful and we really like the DrainAssure WaterWay and the drain cover.  The cover, along with the sound insulation, really quiet the noise from the garbage disposal.  We have now used the sink over two months and it is looking as good as new. We couldn't be happier with our purchase of the Kraus KD1US33B sink.
