The heater is awesome. It warms up my big room.. it smelled a little funny for the first hour that it was turned on it smelled like burning metal, but I turned it off and turned it on the next day and the smell was gone and now it works really good. Had a odd odor when it first started up.

Great heat source

Perfect for the storm backup heat. It works both inside and out and throw's an incredible amount of heat. I was very apprehensive of using propane indoors because of the fumes it emits, but this it great for indoors as a source of heat especially for when the power is out in the winter. Be aware though, if you plan to run of a large propane cylinder, you will need to get the adapter that does not come with the unit.

Perfect for my use. Small to medium outdoor space.

Works great right out of the box. only used it fo 15 mins. but, it heats great for my applications, small to medium outdoor space. Not sure about long term or in wind yet but, it is built strong. As of now i would strongly recommend it.
