Product review (5 stars): Highly Improved from Original Design
These are great--in the last few weeks we have seen each and every one of our old, original front wheel axles break at the point where the little hook meets the axle, and regardless, even when the axles were intact, they kept falling off.  This newer, improved axle snaps, rather than hooks, onto the dishwasher rack, so that the wheel is secure.  Great vendor--received the product fast; I have reordered four more axles to replace the back axles on the rear wheels of the dish rack.  Thanks!!!
