Product review (4 stars): Pleased with Product
This was a good, relatively inexpensive fix for the upper rack rollers.  The only downside, and it is minor, is I cannot fit a larger glass adjacent to the height adjusting mechanism like I was able to do with the original equipment.  Assembly is pretty straightforward and the referenced video helps get all the pieces assembled in the proper order.  This fix appears to be more robust than the original design.
