Product review (5 stars): but the design appears to be much better than the original adjuster kit because it no longer ...
Do the axles holding the wheels on your upper dishwasher rack keep breaking off?  Have you replaced them with the same part only to have them break again within 12 months?  Did it seem utterly ridiculous to you that the axles were molded as part of the entire adjuster assembly so you had to replace the whole adjuster assembly for a ridiculous amount of money?  Then, I would suggest you try this replacement kit instead of wasting more money on the original, poorly designed part.  I've only had this kit around two months, but the design appears to be much better than the original adjuster kit because it no longer relies on the flimsy split axle design of the original set.  As others have noted, there is a good video online to follow when using this re-designed replacement kit.
