I bought it from Kotulas

I bought it as a bday present to myself. I actually was buying it for a fix for fire pit at home. I took with me camping, to just try it. Now it permanently stays in the camper. My buddy bought one too, once he seen how easy it was to use.
Menards sells a similar one, but I like mine better.
