Rattling

Installed in my 2024, 23 ft Shoalwater. Seems to work fairly well I wouldn't say they drain any faster or better than my old flappers. They definitely don't back flow like the old flappers. If there was anything I would try to improve the constant rattling from the balls hitting the outer plastic when they drop. Maybe just a rubber edge guard around the exterior hole? Other than the noise, seems to be a good product so far.
