For the price it is pretty good, however the negatives somewhat outweigh the positives for long term use. Two examples are that the main valve is mislabeled, so while it says twist one direction to increase the flow, it actually decreases the flow, as I was trying to lower the pressure it actually over pressured the secondary, to where I had to take apart the regulator to relieve the pressure on the secondary to allow the solenoid to operate properly. The next issue is that the capture cap on the top of the bubble counter doesn't have the same threading as the bubble counter itself. Thus I cannot secure the line to the top (not that it really matters). The secondary regulator is SUPER sensitive, 1/10 of a turn is the difference between 1 bubble per second and about 10.Bottom line is this, if you are money strapped for your high tech tank, and you are aware of the compromises over the better systems out there then go forward. If you can fit something better into your budget, I would recommend going that way. ### ⭐⭐⭐⭐⭐ Fantastic! *by W***O on May 9, 2019* I was hesitant at first, just due to the fact that there weren’t many reviews on this particular regulator. However, I wanted to take the risk and see if this was a good quality regulator. I had just received it in the mail today, and the setup was quite easy. The instructions are very clear and simple, and so far, there have not been any issues whatsoever with this item. With someone who is just now starting his first CO2 aquarium, the setup was so simple. ### ⭐⭐⭐⭐⭐ My favorite reg so far! *by G***E on April 13, 2019* Best value as far as regs go! Be careful though!
