I had my old Zippos converted to the pipe insert and love them. I was charring the rims of my pipes with butane lighters, but the Zippos are much more gentle and easier for me to control. The fluid used to irritate my leg when I carried the lighter in my pocket, but supposedly the new formulation that is less irritating. Maybe it's just that Zippo tightened the cover hinges, but they do seem more comfortable now.
One thing to keep in mind. They can only put pipe inserts in the standard sized lighters that are about an inch and a half wide. They don't make the inserts for the narrow ones that are about an inch and an eighth wide (I think they're called "Slimline").
