We love our Kraus KD1US33B sink, but the bottom grid that is made to fit this sink is poorly-designed and does not function well. The grid only has tiny plastic "bumpers" that prevent it from scratching the sink, however these bumpers do not elevate the grid off the sink bottom far enough to allow food particles and debris to be rinsed down the drain. Everything but the tiniest crumb gets trapped under the grid, requiring the user to remove the grid from the sink in order to rinse out the sink.  Very poor design!
