Compact. Powerful. Intuitive. This little heater works great warming up the room in the mornings. I don’t know why other reviewers are complaining about Celsius display. Warm means warm! Look up the Fahrenheit conversion and set it to that number! Settings are reset every time unit is powered off. Easy to set timer or adjust temp and fan speed. TIP: DO NOT PLUG INTO POWER STRIPS! WALL ONLY!
