I have to give this 5-stars. It really is excellent and does an excellent job. I also have 2 m-30's, and can't get them to stop leaking. Even my replacement leaked. I say this because they're identical (even the filter element) other than where the hookups are and the size of them. They clearly have a manufacturing issue on the line that makes the m-30, likely with the porosity or the machining of the surfaces. I will reiterate though that this has not affected the M-60, which I'm specifically reviewing here. I just felt compelled to mention it because they're virtually the same.
