I was previously discussing with co2 art whether or not one of their 'dual stage' regulators was a fake dual stage, but they blocked me - maybe I was getting too close to the truth, I dunno. The full discussion can be read here:

The last comment (at time of writing this) by
@rebel linked to a dual stage regulator that was being reviewed by someone on PlantedTank.net, but the regulator in the link that rebel provided is the ‘Advanced Dual Stage’ and it’s the same type as sold by GLA and CO2 Supermarket. I do believe those regulators are indeed ‘genuine’ dual stage, I don’t dispute that.
The regulator I've been referring to and being sold by co2 art as a fake dual stage is the ‘Professional dual stage’, i.e. this one:

They can call it whatever they want, whether that be 'unique' or 'proprietary' it doesn't change the fact it's not a dual stage regulator; it’s a single stage regulator that has been modified to behave like a dual stage regulator, perhaps to eliminate EOTD. So my point here is, even if it behaves like dual stage, it’s not
actually dual stage, and therefore is itself a fake – exactly what co2 art were warning people against.
Let me put it this way; if you stick some feathers up your butt and start pecking around for food, does it make you a chicken? No, it makes you someone with some feathers stuck up your butt pretending to be a chicken, but you aren’t a chicken, and you shouldn’t be sold as a chicken.
No doubt I'll be blocked from replying to this, we shall see.
