I was thinking about buying something like that, but I ended up with a propane brazing torch instead. The kit was $15 at Home Depot.

It's compact enough for me. The self igniting tip is available, but with the amount of lighters around the house from my smoking days, it would have been redundant for me to buy the more expensive self igniting tip.
Reliability wise, it lights each and every time. I've used it to light a grill for grilling nights, braze some solder onto a pipe I was working on, and torch my wicks for my RBA's.
But like with all torches, exercise caution while using them and follow the safety precautions on the label.
