Product review (5 stars): fixed my dishwasher cup rack in 15 minutes.
instructions could have better pictures, but I figured it out and these easily replaced our almost non-functioning, breaking plastic original rack adjusters on our whirlpool dishwasher.  These are solid.  Even though it says kit, I did not read that to mean it was a ful SET (left and right) adjusters).  I thought it meant it was several pieces in a single assembly (which it is), but turns out it was a set of 2, so I returned 2nd order, since i over ordered what i needed.
