Bought as a replacement for the crap burner that came with my furnace. Worked like a champ! Heated beyond the 2500F limit of my temperature sensor.
Pros
βGONGYI
Cons
Not ideal for small-scale projects: The 80000 BTU heating capacity of the GONGYI GY80 Forge Furnace Burner may be excessive for those who only need to melt or smelt small amounts of metal, making it less versatile for those who have a variety of project scales
