Ronson JetLite Torch Lighter

Why is it that a cheapie that works at first seems to work forever, and the expensive ones work great for a while, then get all glitchy and unreliable? Drives me nuts!
As for the Ronson, I suggest buying a couple at least. I ordered 2 from Ronson ($5 each) and one works great, the other refused to light after the first refill. Yeah I purged a couple times, and tried all the usual drills that work. Then I took it apart trying a trick I read about to change the adjuster limit...can't tell if that worked as the lighter never lit again. I get no gas release sound when depressing the "button". But for the price, I can't complain too much.
Long live the cheap lighters!
