It concerns the 0.5 nozzle.
I painted fences 14m long with a zigzag pattern, plus a garage door 4.5m in 6 hours, while by hand it would have taken me a week for sure. I wanted a cheap gun with a small nozzle, the color it sprays is enough for this specific painting, it doesn't need a bigger one, I also have a 1.4 but I prefer this one for this particular job. The negative aspect is the small container, if it had a larger one, 5 stars. If I paint again tomorrow, we'll see, after all, I don't expect much from this price. The important thing is that the job got done. The color used required 2x0.75ml plus nitro thinner.

It is the 1st paint gun that I use for amateur use. I am familiar with a dual-action airbrush with a 0.2 nozzle for plastic modeling. I changed the 0.5 nozzle it has with a 1.0 and painted a five-light kitchen fixture consisting of wooden and metal parts with undiluted water-based paint. It spread the paint very well at a pressure of 2.8 bar and did not require a third coat. I used about 50 ml out of the 75 ml of paint. It cleans easily and quickly. I haven't figured out what the round regulator behind the trigger on the top of the body does, it must not be working.

Awesome gun for small painting, it is very good. Don't be afraid that it is 0.5 mm and some stores present it as an airbrush, you can paint normally. I have painted with oil paint, metal primer, and mini orange especially with the mini brush it leaves lines, with the gun it goes everywhere and leaves a perfect surface for you to apply the color without needing to sand. Really the best I have worked with in an air gun. I am not a professional, I do hobby work for home and friends, but this one has impressed me. It has its own settings for air pressure and paint quantity. Imagine that with 50ml of paint I painted a car wheel, the paint goes where it should and not in the air like with the other 1.4 mm guns. You can even paint fences, I painted a small garden door with 80ml of paint, nothing goes in the air, you adjust the valve to compact and it sprays in a circle of 1-1.5 centimeters.
