Now I have for the next few months (or years .... ?? !!) my butane gas reservoir. with a bottle I can my lurch butane gas burner 10x fill - pocket lighters ca 1 billion fillings ;-) ..... and for the price that is gas unbeatable. the greedy dealer around the corner, you pay the multiples. only the filling adapter in the lid of the can are without use (somehow all the same - just a fake!)
