  • Good value
This has worked flawlessly for the past month. Took a little bit to get the flow rate just right for my application, say about ten minutes or so, but now good to go.

  • Quiet
This regulator has a quiet operation and no leaks so far. It comes with an extra seal as well.

  • Great value and works well.
Great value. Worked well. A little too easy to turn the knob. But good enough

  • USELESS!!!
I’ve ordered this regulator three times on Amazon, figuring that the first two purchases must have both been defective. However, the third regulator is equally useless. I bought this to use in a grow tent for regulating CO2, which is exactly what it’s (poorly) designed to do. The problem is that the regulator is either at way too high of a setting or completely off, and it’s nearly impossible to set in between. My CO2 meter either says approx 400ppm or way off the charts at 2000ppm, and it’s like 1/1000th of a turn to try and get anything in between, which after a WEEK of fiddling with it I’ve still not been able to get it set properly (around 1000ppm). ... show more

  • Meh....
It's ok for what it is. The needle valve is not great and constantly looses adjustment. If you needed a higher flow I guess it would be ok but, when you need a very specific flow it really doesn't work at all.

Works well. Been going for over a month, no issues. Don't expect any either.
