This small heater does a good job of pushing out heat from a small form factor. The topside handle makes it easy to carry. There is a spring-loaded tip switch on the bottom that will immediately turn the unit off when it is not setting flat on a surface. This unit needs to be very close to your person when outside. It does not output the same amount of air as a professional heater. There is no temperature alignment with the dial selector. The selection is merely low to high. The heater does a good job of turning off when the area around it meets the target temperature; you just don't know what that target temperature is. All things considered, I would buy this product again.
