Every one of my 'good' lighters are Colibri ... and I haven't had any trouble with any of them. Not a lick ...
Colibri has been around a long time, and continue to stay in business, and come up with new lighers, when other companies have gone 'by the wayside'.
The key, I feel, is to use the best butane you can find, triple-refined at the very least ... and quintruple-refined, if you can find it.
Volcano LAVA Premium Butane is the best there is out there, at the present time ... and is pretty remarkable fuel. Refined 5X ...
Also, Colibri has a new lighter out now ... called 'The Beam Sensor', in which when the cap is opened, and you 'break the light beam' with your finger ... it ignites.
I saw it at a local shop ... and it's pretty high-tech, and very cool!
