Product review (5 stars): Saved my back
The clips that came with my dishwasher were far from adequate, and constantly popped off.  After a while, I gave up putting them back on and had to lift the rack in and out of the dishwasher - a literal pain.

These replacement wheels have a much better design, and I don't think the wheels will ever pop off again.  I wish I had bought them a long time ago and saved myself a lot of pain!
