Tuning AliExpress Regulators?

There are G1/2 to M18 adapters (on Aliexpress)

But some of those regulators are substandard knock-offs.
Any that claim to be Huben or Cricket are knock-offs.
The adjustables I tried from Aliexpress were unstable.

I use the actual Huben Power regulators. www.hubenpower.com
They are more expensive but the adjustables like the Cricket Max-ATH are rock solid.
That one is M18 at both ends and has a 50CC plenum.
