Very nice paintball regulator.
I love this paintball regulator and more-so the needle valve, super sweet guys. I only wish GLA gave free tubing with the regulator vs having to buy it separate. The regulator is 5 stars all day, but I just feel it should have come with tubing. With that said Im here today to buy another one Hahaha!

Best paintball co2 regulator Ive ever used.
My fish room is in a basement thats difficult to climatize so this space gets some temp fluctuations. This regulator so far has out performed my other regulators. GLA has some magical flow characteristic that makes adjusting the flow so easy and physically easy to see. With my other regulators Im always messing with the needle valve adjuster. I hate always messing with it so I decided to give GLA a try and boy what an improvement. Even my back feels better due to the fact I dont go checking the co2 anymore. I was so happy I came back to GLA today to buy one of the big full sized regulators with GLA's modular valve system. Great products from GLA.

Bad ass!
GLA makes a bad ass regulator and I love it!
-
Excellent Regulator!
I was using a UNS paintball regulator kit, which was absolute garbage and stopped working after only one week (not to mention the eye-watering price). I decided to return it to the store and buy this one instead. Just upon opening the package I could tell it is a superior quality than my previous one. It's been a week now running and couldn't love it more! Would order again!

GLA is the go to for co2!
Been a long time customer of GLA for 15 years now. GLA really knows how to execute an aquarium co2 system properly. All my systems are still running flawlessly after years of abuse.

Finally trouble free co2 for my aquarium.
This being my now 3rd regulator my wife was none to pleased. I tried for two years using a UNS and another Amazon version on my paintball cylinders and none would hold a seal for more than 45-60 days. I think it’s because those UNS versions seem real dinky, and not to sturdy. When I took this GLA paintball co2 regulator out it felt twice as heavy, more substantial. Not only that but I now get 4 months on a paintball cylinder, nearly twice as long. The needle valve on this is also very easy to tune. I’m living GLA co2 regulators.

Highly recommend this paintball regulator.
Now my 3rd paintball regulator. I tried 2 UNS paintball regulators and both failed doing the same thing. They warrantied my first one, second one arrived and instantly was not able to set a normal bubble rate. I dont have a huge tank so this should have been easy. Thankfully I went to GLA and received this. My god, so easy. My bubble rate was rock steady day one and every day. Ok, I can live with this!

Beautiful workhorse.
Very good price and super good quality. Today I come to buy another one for my fish room. Very neat packaging by thew way. I like the artwork lol Installation with this is super easy and I like most that if I want to upgrade one day to full size cylinder I can no problem with the same regulator. Bonus!
-
Good quality and solid build
I bought this regulator after comparing it to other great options out there (UNS Mini, Co2 Art, etc) and found out that the price and the features were very attractive. Even though this is a single stage vs the other options, the GRO's natural decay and rise effect is extremely minimal which alleviates my concern regarding "end of tank dump". Extremely happy with my purchase.
