No experience. I build my own 2 stage regs from ebay parts.
Actually from the pricing I've seen it seems low "if" high quality. That said I instinctively trust Italy over China.
Well they also could be built in China..
Did do some Goggle translate of some of the German ratings.
Seems normal. some said the needle valve was "loose" on arrival but I assume that meant "open" not falling apart.
🙂
Loose would be good since over tightening is a good way to damage one.
You wanted "dump proof" so its a 2 stage.
My biggest worry is what are the native threads on the regulator body ect if I need/want to add remove stuff.
Metric, British, US??
Not to mention the part that attaches to your cylinder.
Oxyturbo from the Aquasabi site above.
If you try to get ones from AlanL or other US "builder from ebay parts" they are high quality but are expensive.
Most would start at US $300.
At one time I tried to find a quality 2 stage China Direct. Found out that what appeared as quality was not actually that cheap.
Besides doesn't seem like a fly by night company and a 3 year warranty.
