Query: Great Product Reasonable Price

This is a awesome heater for what I needed. I puts out ton of heat. You must be careful with it as you would any heater especially a forced air heater. The temp control is awesome and it ran for quite some time with a 20lb cylinder. I ran (seemingly) forever on a 100lb cylinder. Would certainly recommend this product for anyone needing a portable heat source.
