hattrick1972: In my 20+ years of cigar smoking I've learned a few things about lighters and refilling them. Never, ever shake up the butane can. Why? The can contains two elements, propellant (a gas which pushes the liquid out) and liquid butane. Since your vid displayed that yours was a soft flame lighter, it isn't as sensitive as a torch lighter. Shaking up the can, thus mixing the propellant and liquid is a bad thing, it can lead to the lighter not lighting. What you want is just the liquid fuel to go in the lighter. It ensures that the lighter works everytime. You didn't specify what you use your lighter for, but for me, if I'm lighting a fine cigar, I want to make sure there is an even flame where it doesn't go out requiring a relight. (which can happen if the propellant and butane are mixed.) I use Xikar and Colibri butane for my lighters. Vector is a really good brand, also. (they all have less impurities to clog the fuel line.) But then again, the lighters I use cost a pretty penny and cheap fuel will foul the fuel line and the burner. (A little note: It should say on the can not to shake it up. The X\ikar and Colibri cans specify that your shouldn't. Just an FYI.)
crsp76691: I read from a lighter manufacturer that your not supposed to shake up the fluid. The propellent and butane are not supposed to mix.
