I've owned several refillable butane lighters over the years (although I have never tried the Brunton Helios) and not one of them was worth a damn after the first refill. Perhaps I'll give the Helios a try.

I once put one of my lighters in the freezer for a few hours and then heated the butane refill canister with hot water from the faucet just before refilling, and while this helped considerably, I still only got about half the use I did originally when it was new.

I've yet to have a mini Bic fail to light for me except for once up in Wisconsin in the dead of winter. A few moments next to my skin and shaking it briefly got it working again.
