I've had it for a week now, and I've got to say I'm really happy with my choice. I was going to go with something much cheaper, convert a disposable setup into paintball tank usage... But after reading so many reviews, so many problems with all the cheaper i decided to just get one nice system that would be well built and work forever. I'm really glad i did. The needle valve makes precise changes to bubble rate. (I set my working pressure below what was recommended to exert finer control.). I'm really happy. My planted tank immediately took off, algae slowed down.

GLA Pro Paintball Regulator

GLA regulators have been my go to since I began the hobby many years ago. I have never once had a problem with any of my equipment and the customer support from Orlando goes above and beyond what you could expect shopping anywhere else.
