Product review (5 stars): Easy to install -- better than buying individual parts
In the past, I have bought individual parts for the upper rack for my Kenmore Elite and installed them.  Just had a roller break and after much research, bought the replacement kit.  While waiting for it to come, reviewed the Youtube video on removal of the old and installation of the new.  It was so simple -- the hardest part was screwing in those crazy screws ( and I am not always mechanical.)  Works great.  Time will tell, but very happy with the new kit and the quality compared to the original. Don't buy the individual parts -- buy this aduster!
