Last night my Tsubota Pearl EDDIE arrived. (Very cool lighter). I was getting ready to fill it up with some butane I bought at my local B&M called Ronson. But when I bought my Xikar, they said only to use Premium Xikar brand butane so I bought a few of the cans. On their website they say something to the affect that most of the repairs they do are due to people using "cheap" butane. I didnt want to take a chance so I bought their brand. Then.... I recently bought a Colibri and they said to only buy Colibri brand butane. Is this like the battery industry where there are basically only 3 or 4 manufacturers and everyone else just rebrands or is there a real difference?
