I've owned this airbrush for several months now and its an excellent value for the $$. I mostly use this for detail work and almost exclusively shoot enamel paints through it. I've had no issues with clogging while using enamel paints. I have used some acrylics but they have a tendency to gum up the airbrush, more specifically the Vallejo line, although Tamiya acrylics have worked fine with no problems.
The one issue with this airbrush is that you have to keep it clean and you have to be very very careful when taking off the nozzle because its is tiny and easy to break off if you overtighten it with the wrench and they cost about $15 to replace so be careful. Disassembly is easy with everything being finger-tight except for the tiny nozzle. I always flush mine with mineral spirits or alcohol depending on the paint I'm using and give it about 3 cycles in my ultrasonic cleaner. The last thing is that it requires an Iwata brand hose or else you have to purchase an adapter fitting which I did to fit my Badger hose. The last quirk is that I'd recommend applying a little oil to the air valve because the trigger tends to get stuck, giving inconsistent paint flow. So just a little drop of motor oil around the air valve will fix that.
Overall its a very nice airbrush for beginners and those on a budget, users just have to be careful regarding overtightening the nozzle and make sure to keep it clean. I can't compare this to Iwata's higher end airbrushes but with the performance I've gotten so far has been a very good deal.
