Jetmech_63:This kinda got me thinking.....(dumb question....be gentle). I had 2 lighters go bad on me, both single torches and one a colibir. One would only light for about 1/2 a second the other developed a leak at the filling valve stem. In both i've been using Ronson butane(yeah...the stuff you buy at any drug store), did that screw them up? Is there really any diffrence? Look forward to opinions.
