CONCORD 12" THE BLOCK BURNER Single Propane Outdoor Burner. 100,000 BTU Great for Home Brewing, Camping, Tailgating, and More!

Lightweight, portable, seems well built. This thing gets this hot fast. My wok also fits on it. Works well. Does not leak gas.

very sturdy. powerful burner. compact. great price

Purchased this for canning with a relatively large (7 quart jar capacity) aluminum pressure cooker that no longer works on my stove (switched to induction). Took 30 seconds to assemble. Worked like a charm. Flame is steady with good adjustability and plenty of heat output. Frame is sturdy. Cast iron is naturally brittle so having the bottom framed with crossbars (rather than free-standing legs like some other units) offers additional protection to the burner when storing. Functionally, it's 5 stars (after initial use; will edit post if longevity becomes an issue). Enhancements to make it perfect: 1) integrated piezo igniter and 2) engineered to store more compactly. The main point of a unit like this (IMHO) is portability. The cast iron burner unit extends several inches from the frame and after connecting the gas line, the entire unit is clunky to store. I'm sure the same applies to other units, but seems like it should be possible to engineer so that it collapses cleanly into a cube.

I really liked this burner. I used it for cooking with my wok. It has a cheap regulator though, it broke and I can no longer control the flame. Replacement regulator was more than the burner new.

Super great product, I do recommend 100%.
