Product review (5 stars): not just in the rollers but also the cable itself looks to be higher quality and better molding to the plastic ends
Hardest part about replacing these was sliding the dishwasher out to reach them.  The actual replacement is about 2 minutes per side, and these work perfectly.  The design is different from the old one, not just in the rollers but also the cable itself looks to be higher quality and better molding to the plastic ends.  My local repair tech wanted $300 parts and labor to fix this.  My son and I did this in 30 minutes for $17, and I'm NOT what one would consider "handy".
