I think I'm missing something here ,if the nozzle head is fixed how do you replace the nozzle ,how can it be removed to give it a good clean. Etc or am I getting confused on terminology here . With regards to the cups I have some coloni cups / pots. Like mini syphon pots ,might give them a go ,I doubt the adaptor will fit as its for an iwata . So painting wise ,if you've had the chance yet how does it compare to your regular sotar ? .
