Product review (5 stars): Cheaper than replacing our dishwasher!
These are the classic necessary evil. They keep our dishwasher from leaking. Unfortunately, they get dry and brittle and crack about every 6 months. It is no doubt made worse by the desert climate we live in. Our dishwasher works perfectly besides having to replace these. I've learned to keep an extra on hand as well. These are much cheaper here than locally.
