Product review (4 stars): Better than the stock ones
I was skeptical, but these fit my Kenmore dishwasher. I'll start by saying that I don't love my dishwasher. It's about 4 years old and this is the second time I'm replacing the top rack adjusters. This product is much better than the all plastic one that came stock. The wheels are held on by a way-more-substantial piece of plastic and a screw that's fastens them to the metal part of the adjuster. The delicate piece that holds the wheels on is what had broken in the past. The rack is still not the sturdiest thing around, but I have confidence that this replacement part will hold up for a good long while. A note to the manufacturer: your instruction book is printed very dark. Hard to make out the images.
