Product review (4 stars): Bought again and again.
I have replaced this part on my dishwasher several times.  It is easy to replace and works fine.  I only give 4 stars because I think they need to develop one that lasts longer or has more strength.  If someone is not careful when pulling the top dishrack out to load/unload the dishes, it can easily break the little "axles" that hold onto the roller wheels. This causes the other roller wheels to become stressed or unbalanced, and they will also break.  I have my children help with dishes all the time and sometimes they forget to be gentle.  I guess I expect a dishwasher to be built sturdy since it gets used on a daily basis.
