Review on 🐠 FZONE Aquarium CO2 Regulator: Optimal Paintball Solution with DC Solenoid, Aluminum Alloy Bubble Counter, and Check Valve by Holly Smith

I bought 2 Fzone regulators a few weeks ago, this one is defective, Co2 is leaking from connections. UPDATE: I can't say enough good things about FZONE customer service. My first device didn't work properly so they contacted me and immediately sent me a new one. I can say with full confidence that you can feel comfortable ordering FZONE products! Most of them work great, but if they don't work, the customer support staff will fix the problem. Great job Fzon!
