Product review (3 stars): Whirlpool/Kitchen aid plastic is bit brittle
This isn't a ding against this product per se. This is a ding against the plastic being used by Whirlpool and Kitchenaid. It seems the heat of dishwasher makes this plastic brittle and easy to break. I ordered two of these because just looking at the frail spindle, the plastic that holds the wheel is bound to break again.

Following the advice of another post, I did use epoxy rated for high temperatures and filled in the gap on the spindle that holds the wheel. Hopefully this will reinforce it and keep it from breaking again.

It's ashame whirlpool/kitchenaid made this so easy to break.
