Product review (5 stars): Worked pretty well without the glue
I am renting, and the dishwasher is starting to leave rust marks on my dishes. I didn't want a hassle with the housing people, so I bought these as a cheap and easy fix. Since I may want to take them with me when I leave(and I didn't want to spend the money on the glue) I just stuck them straight on. Out of the 100 caps, only 7 or 8 came off. They got stuck to the plates and some were in the drain at the bottom. I super glued them with just one tiny drop of glue, and they haven't budged since. The best part is that my dishes don't have rust spots after each wash.
