Used it last night and I loved it! Feels great in the hand, lite every time on the first try...including playing with it for an hour or two ..., and I really like the single flame. I feel like it gives me more control and precision and I don't feel like I'm trying to light my cigars on the back end of an F-35.
Anything over a single flame is overkill and actually may do more harm to the cigar than good.
The quad gets it done quick - 3-4 cigars and its time for a refill and easy to scorch your stick.
Triple is pretty nice and quick, but can still burn too much.
The single has precision, can have a large flame ( i set it just below mid) and i have yet to scorch or burn more than intended.
Butane also goes a lot further.
