Yeah the stock needle valve in the cheaper models looks the same as
my Azoo's and Aquatec and tons of other regs from China. It's hard to adjust,
hard to turn, too coarse. But it holds.

For some people, the problem is not the cost of CO2 gas (it should not be,
as you have said). It's the hassle to refill or to find a place to swap the
cylinder.

I can find just 2 reasons not to use silicone tubings for our CO2 application:

1. You use a push to connect fitting. Silicone tubing is too soft for it to grab firmly.
This is a reason why ADA...

What I think is that section is flattened because the CO2 is drawn from it but the water
