"Refilling is possible"
I have had a Lakeland gas lighter for many years (similar to but not the same as the current one). I find I can use the nozzle already on the can of fuel, and don't need to add a different one. Sometimes there is slight leakage and it is a bit tricky making sure the nozzle is precisely centred on the inlet of the lighter, but with a little patience it is perfectly possible. I wonder if some reviewers are making the same mistake I once did of trying to refill into the top of the lighter instead of into the hole in the bottom?
