They put out good bubbles, they DO NOT stick to the bottom of the tank. None of them. For longer than 2 minutes. So that’s extremely disappointing.

It’s an air stone. I don’t know what kind of review to give. Yes air comes out of it and it sits in the fish tank and it’s cheap.

Almost all of them stopped producing bubbles after a few months. I clean them and they work for 3 or 4 days and then stop working again. I have several different kinds of air stones and these are the worst.
