Review on 🌬️ U.P. Aqua Brass Bubble Counter & Check Valve: Optimal Air Flow Control for Aquarium Enthusiasts by Karen Cooper

I have some sort of CO2 regulator and the bubble counter has snapped. I ordered this due to the brass fittings and the fact that the regulatory company is overseas and I was concerned about the delivery time. I'm quite satisfied so far. I put this on my current regulator (best in line, I might add) with minimal adjustment to my settings, and my reset check turned green within 1.5 hours of use. It looks like a stable CO2 supply. Although the English writing on it is obviously a Chinese translation/product, it looks solid. However, I have a limitation. The plastic cylinder could have been thicker (like the CO2 Art product) but I remain optimistic.
