After having like 20 or so torches specifically bought from head shops and vape stores all die in less than a year, I said "fuck it" and bought a kitchen torch from a commercial kitchen supply store in the area. I've had it for 6 years now with no issues. Plus I can actually make the cool caramel crust on a creme brulee now when I'm not using it for dabs.

You could also go with an acetylene torch from a hardware store. Those are sturdy, and the propane tanks last fuckin' forever if you're just using it for smoking. Though, they aren't easily portable.

Hey! What does the trigger do instead of spark? I ask because on a somewhat similar torch I had the trigger would depress with resistance but not sparked. I fixed it by greasing the moving part inside the plastic piezoelectric igniter.
