Pros
- 125,000 BTU for about $157, very little per BTU
- Shuts the gas off if the flame goes out, and cuts out if it overheats
- Hose and regulator in the box
Cons
- Empties a 20 lb tank in 3.5 to 4.5 hours by VEVOR’s figure, so it really wants a 100 lb tank
- Only turns down to 100,000 BTU, too much for a small garage
- No safety certification named and no manual published
