There are two things that are fantastic about this regulator. First, it is like a scientific instrument. It is made from brass and really high quality fittings that have been assembled by a human and everything is perfect right out of the box. The quality is really remarkable all around. gauges are super easy to read, bubble counter and airline input are very high quality. The second thing which may seem trivial unless you are an expert already at CO2 is the instructions. They are simple and perfect. I never could have figured out the Chinese version I almost bought. there are a lot of steps to doing it right and doing it in a way that does not fry your solenoid or low pressure valve.The instructions are almost worth the price of admission. Love a well made tool.

Had it running for around 10 days now. Easy to setup, all in one unit. processing was a bit slower than I would have like but fast shipping and quality packaging. I will be expanding upon this regulator in the future.

Regulator and customer service
I purchased this system just over a year ago. It has worked perfectly. When I did have a slight problem I contacted them through email. My email was answered very quickly, and he helped walk me through how to clean a party fix my problem. Quality of product and customer service is top notch! Highly recommend this product and company.
