The function on this catcher does well. It does a great job catching the ash. On the down side some of the hurb can still hop into the bong it self if filled a little too much. Really easy to clean the chances of there being something left over after a clean. One main problem I noticed is when cleaning is that when the bowls are wet it will be harder to remove or during a session if it becomes stuck the catcher can be lifted off your set up.
