Barbed fittings: Good or bad?

I used the push-lock fittings on my fuel system for the fitech, and plan on using them for the trans cooler lines. When used with the appropriate hose, I could probably hang off them. They are SOLID. They DO NOT use clamps.
There are different tricks to get the hose on, heat gun, boiling water, etc, but I used this tool with a few drops of wd40, and it couldn't have been easier..
