Product review (5 stars): Quick and Easy Fix for our Kenmore Portable Dishwasher
Exactly what I needed to fix my Kenmore portable dishwasher!
Simple instructions were included.  Total fix took about 5 minutes (with an added 15 minutes - I soaked the end of the hose in vinegar to remove any deposit buildup before putting the new pieces on.)
No tools needed.
The old coupler (5 years old) failed spectacularly yesterday afternoon (impressive fountain and all), we paid $4 for overnight shipping, and it is fixed 24 hours later.

It's a month later now - I feel so foolish for waiting so long to replace our old connection!  So happy we did it.
