Product review (5 stars): Great replacement for flimsy factory original !
Totally worked as the replacement assembly for a broken KitchenAid adjuster.
Based on other reviews I skipped the provided instructions, and went to YouTube for very clear and video instructions.
My kit included a hex tool attachement (that you can place into the tip of a regular Phillips screwdriver).

While is too soon to tell how long is going to last the design looks as an step up from the original Kitchen Aid, metal replaced a lot of the plastic assembly.
