I'm up and running now. I was going to take photos and pour over the post but decided to keep it simple.
The difference in build quality between this and my Scythe Kaze Q-12 is huge. It's like a Tank vs a Smart car. That's front to back, too. The metal parts and heavier and thicker, the electronics on the other side is where I seen the biggest difference. Everything is tidy, really chunky and solid. The Scythe had bits that would bend sticking out the back if you looked at them the wrong way.
The throttles/knobs/sticks do pull off but you need to pull them. They wont drop or fall off. The cables aren't braided and are the regular old red/yellow/black kind. I would have been a bit unhappy about that if I didn't have the braided splitters ordered at the same time. I've just left all the stock fan cables in the box. Also, the cable you can't replace, the 3 socket molex power, is really short. I was pretty happy with that, it means the only visible cables from the side view are the braided splitters and my PSU cable going up to meet the controller. If you are low on molex power connectors and/or your power cables are on the short side, that could be an issue.
About the actual fan control. So far it's been far better than I had hoped. The fans do switch off completely if you push down the slider but more impressive than that, the tone of my fans seems to have changed for the better. Even turned up a good bit it's just less intrusive a sound. Turned all the way up they sound like they are chucking out a lot more air. This might be more to do with the Scythe being rubbish than the Lamptron being awesome but I'm delighted.
