I'm only gonna chime in because I have 2 cadlights pipless skimmers running.
They are the hardest skimmers to dial in, period. With no air intake ajustment and having to turn the body of the skimmer it's really hard to find that sweetspot everyone wants for a nice dry skim. The newer ones like yours are better (they sent me a free one) because you can at least lock in a setting and hope it stays there.
Most important for this skimmer is maintaining the water level in the sump. I built a chamber that no matter how much evap I have, my middle chamber stays exactly the same so the cadlight skimmers keep working. If the water level goes up a bit they over flow, down they don't get the bubbles in the cup at all.
My first gen was horrible. It worked for like 2 months and then completely stopped working. The body would move on its own and the thing would overflow daily. I wrote to them and they sent me a better one that now maintains a constant level but I still really struggle to find that spot that produces dry foam that acutally makes it in the cup.
Sorry for being a bummer but thats just some of the issues I've had with these space saving skimmers they came out with ...
