Review on Ivation Propane Torch with Easy Trigger-Start Ignition, High-Temperature Flame [2372°F], Adjustable 🔥 Flame Control - Ideal for Light Welding, Soldering, Brazing, Heating, Thawing & More by Scott Rao

As mentioned, the ignition just stopped working - in my case after a few days of use. The button still had the same mechanical resistance and a sharp click when pressed, so it didn't look like a mechanical failure. There was just no more spark. Also worth noting: the gas supply valve was not tightly closed. Drained almost a full cylinder overnight. I capped a full bottle, made sure the valve was tight, and brought the nozzle to my ear. The hiss of escaping gas could be heard. It was a good product for a short time and based on the reviews it works well for many buyers. But some buyers describe these different failure modes the same way I do. Failure of the ignition function indicates hidden component defects. Inadequate sealing indicates design tolerance issues and/or manufacturing variability. That.
