I have had a number of windproof lighters and they seemed to not work after a while. At the tobacco shop I mentioned this and they said the quality of butane is important. Colibri and other good quality butane (such as found at a tobacconist) will not cause your lighter to fail. I think there was a thread not terribly long ago about the quality of butane. The tobacconist said that there is a way of filling and purging a lighter that sometimes loosens up whatever is causing the blockage.

I use a Windmill lighter which Doug had mentioned a long time ago. They come in a number of colors including glow-in-the-dark light green. The only problem with the lighter is if the lighter is in a trouser pocket with a lot of other stuff the button releasing the cap gets pushed and the cap opens.
