Review on Worx WX742L 9 20V MAKERX Brush by Wayne Drakh

Airbrush, received it last week and tested it today. I'm a fairly experienced airbrush user, but from the moment I added some paint and started testing the drawing, it kept spewing paint and the paint siphon kept bubbling. I tried adjusting the drawing, increasing the amount of paint, but the problems still appeared. I decided to check the nozzle and as soon as I unscrewed the two outermost nozzles a tiny piece of "k" fell out. I thought it needed to be screwed back up, but that didn't happen. At this point, my hands are covered in paint. I then decided to clean it and see if it comes back, but it doesn't. Then I looked at the piece under the microscope and found that the piece that fell out was indeed broken. I can't give a good rating until I can test the product, but that's not possible with defective parts. What should I do? I don't think I should pay to replace a broken tip. I am very disappointed because I have two projects to finish by tomorrow.
