AC Infinity CO2 Regulator, Carbon Dioxide Monitor with Solenoid Valve and Gas Flow Meter, CO2 Gauge Gas System for Grow Tents, Grow Rooms, and Greenhouses

Threading of the nut that goes into the tank not good and also you need adapter for the power cord as it is Chinese

Arrived damaged, the thread of the nut which screws onto the tank was damaged and wouldn't screw on. Not acceptable.

Ótimo produto Muito bem feito , prático , durável , resistente . Marca top . Recomendo.

2 years still working

Better than my previous $150 bubbler setup Ac infinity has great products 100% recommend

First one was used and dirty, second one does not work. I think the 2nd one was used too. The instructions say to use a wrench so at least it will be obvious to the next person that this one is used as well. No air flow. Does not work at all. Shame on you ac infinity

Well made and solid but not without frustration with my initial attempt at CO2 distribution. This is not a flaw with this product, but with any CO2 regulator in general. My first unit was returned due to no flow, had been previously returned and sent out as new due to the damaged box, dirty condition and tool marks, thanks Amazon. Paid full fare as they would not accept my coupon code but were more than happy to send out a non-working item. Replacement arrived and although brand new and apparently untouched by consumer hands also would not pass gas. Decided to call ACI for assistance but had to play the email game and got little advice other than replacement. Opened a ticket and after 10 days received a new one. Guess what, this one also would not pass gas. Decided that the best course of action was to take it apart and low and behold, found a microscopic piece of debris which was plugging up the works inside the regulator chamber. Had tank pressure on the gauge but that was it. Put it back together and it is now working like a charm. Again, we're talking a spec of debris so small I could barely see it but was large enough to plug up the works. This is not a bash, but an FYI for those who may come across this problem with this item or any CO2 regulator for that matter. Unfortunately customer service could not deliver any insight other than replacing the item. Be sure to release a small blast from your tank prior to connecting the regulator to as a precautionary practice. Would have given 5 stars if Customer Service Rep did more than apologize for the inconvenience, and actually put me in touch with real tech support. All in all, happy to have a working CO2 system after 3 weeks!
