Product review (4 stars): 1 Wheel down, 7 to go
I put these on and ran the dishwasher several times over a 30 day period.  I was concerned as they are plastic and not secured to the carrier in place with any metal screws or anything.  The wheels just snap in.  After the 10th wash or so the wheel came off after the plastic carrier  of the wheel gapped open too far for the wheel to snap back in.  However for the price, not a bad option provided not more wheels come off and the carriers do not gap open.
