As the title states, this works really well. It's nicely sized, produces a consistent bubble stream, and the bubble counter is an added plus. I've used it for about 3 weeks and it has been perfectly consistent.
Finer bubbles than the glass ceramic diffuser but I haven't tried to clean it yet. It does require a little higher pressure then the glass ones and is bigger. I am able to get a nice stream of fine bubbles to come out
