These use the same parts as the infinity model, with a few missing features. But the needle options are great, the cups SCREW OFF, you can actually change you cup size and if you have some paint build up, easy to soak the cup or you can dunk the AB into a container of Createx Restorer, so much easier than if you have a large gravity feed cup.
Replacements parts aren't ridiculous cost
PTFE seals so you can use solvent
Nozzle is floating self centering and large, so it's a lot easier to work with.
