Review on 500,000 BTU Economy Propane Torch Kit - VT2-1/2-24Ce by Sean Maples

I use it once a year for edging and weeding a long gravel road, works great as intended. If you see a few weeds reappear after a few months, remember that the seeds may explode and germinate, that doesn't mean it hasn't been effective. It's really nothing more than a rooftop lantern that has been used by contractors for decades, yes it's loud and yes you can set things on fire if you're not careful, but it does the job perfectly. I always have someone nearby with a garden hose and I also wet the entire area after I'm done to be safe. It uses a propane tank 20 pounds faster than a BBQ grill, but that's to be expected.
