I have always used gas lighters to light my candles and BBQs but not very environmentally friendly so I thought I would give this one a go, and I love a gadget. It did stop working even though the lighter showed it had charge left, you just need to make sure the two prongs are clean and wax free from the candle you lit the night before. I Simply wiped that off and I was good to go again. I have since bought extra now for my family, great stocking fillers.
