Product review (3 stars): One star lost because of the poor quality of the instructions
It's only been installed for a few days, so I cannot comment on the reliability.
One star lost because of the poor quality of the instructions.  The dark black and white pictures are very difficult to see and the written instructions rely heavily on the pictures.  It took me 20 minutes to put the first side on, and 1 minute to put the second side on.
The other star is lost because the height adjusters protrude much further into the rack than the originals.  I much prefer the original design, and what was changed in this design did not address what required me to replace the part, which was the plastic retainers for the wheels breaking, as they remain the same.
