I have read all the reviews and looked at other products. My brother has a Milton that belonged to my father who was the chief mechanic for the US Air Force and Los Angeles City General Services. He worked on garbage trucks, and they all used Miltons. As other reviews have mentioned, you can easily disassemble the air cartridge and use a round file to remove burrs on the edges where the hose goes through. You get a quality product at a reasonable price because they save a corner or two in production. With minimal maintenance, you get an air cartridge that will last for generations.
