Query: Very disappointed

This paint sprayer was a birthday gift. I should have read the reviews before opening the package because it would have saved me time and my son some tears. Only one side of the sprayer worked from the get-go. No troubleshooting that I attempted helped to solve the problem. To make matters worse, the paint simply drips out. The picture on the box is very misleading. Obviously, I'm not the only one who has had this problem if you've read other's experiences here.
