This item arrived quickly and works well! Solenoid doesn’t get hot and the bubble counter works well. The bubble adjuster worked good too!

Works perfect, just as good as the expensive name brand ones.

After doing hours of research on CO2 regulators, I couldn’t justify spending $200 on a regulator no matter which way I went. I scrolled through amazon until I found this guy and it had one review. For the price, I was willing to gamble. I’m soooo glad I did. This thing can be adjusted to below one bubble per second and brought my CO2 levels from unacceptable to great in two days. I highly recommend this product to anyone just getting into the CO2 aquarium injection game.
