Product review (5 stars): Fantastic dishwasher upgrade -- should have come this way in the first place
This is a fantastic replacement for the top rack adjuster that came with our 2011 vintage Kenmore Elite diskwasher and has broken twice -- I actually kept the OEM part in my Amazon saved orders and was about to re-order again when I ran across this kit, which includes both sides for less than the cost of two of the OEM parts.  I can't say enough about what an improvement this is on the cheap plastic parts that shipped with this $1400 dishwasher.  It was very easy to install, although the photos in the instructions are somewhat dark and blurry. There is a YouTube video mentioned in another review that was immensely helpful -- especially when we realized that the push are left-and-right specific, while the original kit can go on either side.  After taking 20 minutes to replace one side, with that experience (and finding the TORX screwdriver extension that works on any Philips screwdriver), it only took 5 minutes to do the other side.  Now the rack feels much more solid and doesn't slip down to the bottom position every time I pull it out.

While there are still plastic parts involved, I suspect this will last much longer than the original parts -- hopefully outlast the dishwasher.
