I was looking for a new Dual Stage Argon regulator and saw this one posted in a thread on here somewhere: Link It seemed to be significantly cheaper than everything else out there so I thought I would take a punt and see what its like. There wasn't any follow up to the suggestion in the other thread so I thought I would do a couple of tests and post the results. Build wise its pretty good. The Gauges are obviously cheepies but the reg body seems very well built and has some weight to it. Initial surge control seems good, significantly better than the other single stages I could compare against which were bouncing off the top of the flow meter: Link It also does a very good job maintaining flow with varying cylinder pressures. Here's it seeing 180-0 Bar and keeping constant output pressure to the very end: Link If anyone wants any more pics/video, let me know.
