Works well. Blutooth interface is a bit wonky, but once you get the hang of it, it works.
This heater uses notably more fuel than my other (upright) 8k heater. Not sure if it's putting out more heat, or if it's a setting. It's kind of hard to tell what the setting is - would be better with a simple Low/Med/High instead of the multiple numbers.
