Product review (5 stars): Perfect Fit
Exactly what I needed to replace the original rollers.  Replacement was fairly easy.  The most difficult part was removing (without breaking) the triangulr plastic retaining clips that hold the rollers on the axle.  These wheels do not come with new clips so you might want to order some just in case you break one in the process.  No clip = no work.  Videos are available on the web to show how to go about the replacement process.
