A part of the review has been auto-translated.
A dual action trigger and canister at a low cost. Everything received as advertised. I tried it with water and then alcohol. It works but it took a little fiddling to get it spraying adequately. Next I tried 2 drops of cheap acrylic mixed with alcohol. It was too thick though so I added more alcohol but the needle was sticky. Used blow back to mix and free the needle. It worked but was spotty. I cleaned it up and will try again. Of note I wasn't using airbrush paint. I think the cheap acrylic will work but proper mix rate and mixing agents will be trial and error. I'm satisfied with my purchase. This obviously is not a professional airbrush but I think it will work for basic tasks. Plus with the adapter I think you can use a different and better airbrush pen.
Although the boxes arrived damaged, the small airbrush seems to be working well, I will have to do some tests to see the actual capabilities, but for now I am happy that everything arrived working. There are no clear explanations on how to clean it and do maintenance after use and the paper alone is not the maximum clarity. I hope I can use all the colors for airbrush for modeling... we hope!
