I don't own one, but know people that have them and really like them, the lighter from Mark's company Palio, I've used them a few times and do like them, some of the features are a lot like the St. Dupont lighters as far as the flame adjustment control and the removable cap to access the refill nozzle / valve. I believe much like their excellent cutters they too have a lifetime warranty.

Personally I use one of the knock-off Power lighters, it's been reliable for the last couple of years, I also use the freebie lighter from SoCal last year as my daily lighter.
