Product review (5 stars): Don't mind helping to load the dishwasher now!
One of the wheels was missing from the lower dishwasher rack when we moved in to our 'new-to-us' older home and the rack would always get stuck where the door-to-dishwasher joint is. It was especially annoying when the rack was loaded up. These replacement wheels were just what we needed to fix the issue. I ended up replacing the other three since the old ones looked so dingy when compared to the new ones.
The wheels and mounts look exactly like the factory ones that were getting replaced and were easy to snap on. They still look good and roll smoothly after 2 1/2 months of use.
