I have been extremely pleased with the performance of this sprayer. I have sprayed professionally in a dedicated spray booth with professional equipment and this gun certainly does not match the quality of that equipment but it is not thousands of dollars either. I am currently using it in my small garage shop with a 40 gallon tank air compressor and it runs well above my expectations. I've used several other siphon guns and HVLP spray guns with very unsatisfactory results. The main issue that I have had in the past is not being able to get enough volume of spray out of the gun. This is directly linked to the thickness of the finish and the size of the orifice in the spray gun. Most spray guns have a 1-1.4mm tip which in my experience is not enough to spray water based polyurethane which is what I primarily use. The 1.8 mm tip on this gun handles water base polyurethane very well. I also have found that the air control capabilities of this gun are better than others that I have used. The only reason that I have given this gun four stars rather than five is because the gun came with a dent in the metal cup. It is still usable and not a big concern for me. Overall I'd highly recommend this gun for anyone wanting to spray water-based polyurethane.
