Product review (5 stars): Better than original - Couple Quick Tips
Like everyone else, used this to replace the broken plastic original parts (on our Kenmore).  Replacement took me 15 minutes.  A couple words of advise...

1.  The Instructions are lacking.  Youtube has a great walk-through (about 10 minute video).
2.  When installing the metal main-body, make sure you put it through the lower portion of the rack (below the cross-member in the middle).  The video left this off and I initially installed it in the top which added a bit of time as I had to figure out what I did wrong.
3.  They included a Torx-15 adapter in my box...I had a Torx tool so didn't use it, but it appears you no longer need to buy the tool if you don't have one.
