Product review (3 stars): Fits exactly in model
I am giving this a 3 star, as since I couldn't find my original purchase receipt, I am ticked at LG for having to pay for a new rack.  I have NEVER had one rust through, and once it starts, several prongs will appear damaged within the week.  Too bad the upper isn't sold on Amazon, as now a week after installing the lower, I had to order the upper.
Should have walked to Bosch or other when read LG covers this for 5 years in its warranty
