Good rubber stoppers but tiny holes renders them difficult to use.

My only complaint is the time it took to arrive. Everything about the rubber stoppers is as expected.

This RS-10-2 size fits the Five Gallon clear plastic water jugs. I use them to form a Cascade system when running my RO/DI System when making reserve water for my Saltwater Aquariums. The Lee Hard Airline fits perfectly in the holes. Just make sure you don't plug the last one. But let it overflow into a bucket, you can check on.
