Have had this airbrush for several months and has had a fair bit of use. I'd say it's hard to beat for the price point. Have mainly used it for priming and base coating, which it does like a dream, and it certainly has the potential to do more sophisticated work; especially if you switched out the 0.3mm needle for something smaller.
I don't know if it is engineered as well as the more expensive options out there, but it feels solid and high quality, and it certainly functions just as well as the expensive airbrushes I have tried! Trigger control is nice. It's just as modular as the fancy options, so can take it full apart for deep cleaning when required. Ultimately, it is a cheap option which doesn't feel or function like something cheap at all. Highly recommended!
