I purchased this unit in November 2019.
                    It looked small but I gave it a chance.
                    I do woodworking on my 2 car garage.
                    I set it at approximately 65 deg. I turn on the switch and about 45-60 minutes the space is up to temperature when the outside temperature is between 30-40 deg. and keeps it at temperature all day. Here in Kentucky it can get to single digits and the unit works well. It beats messing around with a kerosene.
                    It was easy to install and wire it up.
                    I would buy this again.
