Product review (5 stars): Fixed a long standing problem with dishwasher.  Improved with Modification.
Brought our Dishwasher new life.  My wife was continually griping about the broken guides, and after loading the dishwasher myself one too many times and struggling with the lousy broken stock guides, I replaced them with these units.

I did the epoxy mod suggested by another review and so far 6 months later, no cracks.  It feels like the epoxy addition will completely fix the problem with the wheel locators cracking and falling off.  It was a significant pain in the ass to round up epoxy and pour it, but if it continues to fix the inherent design flaw in the adjustors, it was worth the effort.  Thanks to the other reviewer for the recommendation.
