Quality regulator and very heavy duty

I have real working knowledge of CO2 and regulators, I went with GLA because those who owned GLA regulators swore by them and really love them. They are certainly quality regulators. If you have owned any generic brand before, forget what you know about quality co2 systems because GLA has set the bar. This was easy to see since they invented the modular manifold years ago, now china is producing knock offs. I did look at co2art, but if you pay attention you will notice something. They mention in co2art the regulator is made in Germany, its 100% made in China. How do we know this? Because you now see the same regulator rebranded under many other names sold out of China. Shame on Co2art for lying to customers about where their product is made... Congrats GLA for staying the source and building US made products.

Best Regulator I’ve Used

This regulator is amazing. Sturdy. Made of brass (and not chrome). Dials in super-accurately and stays there. I can’t recommend this enough. Invest in this to start with and avoid the headaches that come with other regulators.
