I know this is old, but I figured it would be better to post here than to create a new topic.

I've tried this method personally, and no matter how tight I pack the pen, the butane still blows straight through it, just leaving a VERY small amount of sticky substance on the aluminum tray, which amounts to practically nothing.

As said in the first post, if the butane blows right through it, it won't work properly.... But no matter what I try, that's just what the butane does.

Any help?
