## Customer Reviews

### ⭐⭐⭐⭐⭐ co2 release seems off if you try to meter it ...
*by S***. on August 22, 2014*

co2 release seems incorrect if you try to meter it down to 0.1cfm - but otherwise works well, to work around i release at a higher rate for a shorter period. this unit is not noisy, but as noted by other reviewers the solenoid hardware can get hot. since i only run it in 15 minute 'bursts' every few hours, it really doesn't matter (it doesn't affect my ambient temps, and my ppm never drops below 1500.)

### ⭐⭐⭐⭐ Seems to work as suggested
*by $***T on July 17, 2023*

I would probably just go ahead and spend a few more dollars and get something on monitors and cuts on and off as needed, this is controlled by a timer and hard to really dial in the proper levels

### ⭐ Poor quality product
*by T***R on November 9, 2011*

Regulator will not hold settings, especially the lower ones required for smaller areas. The thing is also very hot! Enough to burn your fingers when adjusting (or attempting to) the output. Bad Product! Contacted the seller.....all I received from them was attitude.
