Product review (1 stars): Works as well as original.  However you now have better options.
The design is faulty (I've had five break since late 2012)  The "clips" that hold on the wheels just don't hold up.
But it works as well as the original.

After that last break I found and ordered this part instead: "Whirlpool W10712394 Adjuster KIT"
That other kit comes with all that is needed to replace the adjusters and all that holds it to the wire shelf.
Looks like it should hold the wheels on much longer than this W10350376 kit.
