I bought this because my previous diffuser produced bubbles that were too big. This one works well for the level of CO2 I'm spraying in my 75 gallon tank. Probably not suitable for tanks under 50 or 60 gallons. The CO2 I use doesn't even use the entire surface area to create bubbles, meaning 2 inches is for larger tanks. Otherwise work well, small bubbles, definitely "fog". It goes without saying, but - it's glass and therefore fragile.
