Review on FZONE Aquarium Regulator Compatible Paintball by Mary Campbell

I ordered the FZone controller on July 22, 2020. The package arrived quickly on July 24, 2020. I installed the regulator and opened the CO2 supply as instructed. Everything worked for 2 hours. After 2 hours of use I noticed that the bubble counter showed no CO2 in my tank. I turned off the CO2 from the system to ensure my source was still filled with CO2. As expected, the CO2 storage tank was full. I then contacted the seller to find out what the problem was. The seller replied that most likely the solenoid valve was broken and he wants to send me a new one. Of course I agreed. Two and a half weeks later I still have not received the solenoid and the seller has stopped responding to emails. I have ordered a new CO2 regulator for my aquarium. I'll write a review on it when I get it. I had high hopes for this controller. When I received it the valve was stuck. It comes with a bubble counter and a check valve. However, the solenoid valve was not strong enough to rely on. Also, the seller does not respond to emails or issues. Unfortunately, I advise against buying this product.
