The 'H' series is a single action airbrush which means that when you press down on the trigger you are only controlling the airflow. To contol the paint flow, you have to ajust the paint nozzle and tip assembly which is very, very easy to do. I also have the double action V or VL series. Have'nt looked at it for so long I can't remember the series. With the double action airbrush you must push down on the trigger for airfow and at the same time pull back with the trigger to control paintflow. I hope I did not confuse you with the details. I have used the 'H' series exclusively since I bought it in 1992 and have no complaints but do remember to keep it clean. Ther are other brands out there and they may be more inclined for the beginner it's just that i have never strayed from 'ol faithful'. Hope this helps you out. Jon
