Product review (3 stars): OK replacement for Kenmore 665 series dishwasher
Update:  3 years in and it's rusted out pretty badly.  Have to replace it again.  There are many materials in this world that don't rust - why don't they make these things out of something else??  Still better than the original, but it's crazy to have to replace these things so often.  Sears parts direct has a replacement that is a different color, so I will try that one next and see if it's any better.

Bought this for our older Kenmore dishwasher (665.1383) and it fits perfectly.  It's actually better quality than the original that we had (that one rusted out almost immediately) and is way less expensive than getting it direct from Kenmmore.  It seems to have a better sealant over the structure.  The only thing it's missing is the "rear tine row", (the very last row of tines that is removable), but you can order that directly from Kenmore for about $30.
