Dual Control System Two control methods make our life more convenient: the remote control allows us to easily control it from a distance, and the panel control makes our control more direct. Quiet & 12 Hour Timer This infrared space heater is super quiet when heated, and will not disturb you at all. And it also has a timer function, which keeps us from getting too hot when we fall asleep and also saves electricity bills! Child Lock & Cool Touch The child lock can prevent children from being harmed by random operation, and the wooden frame can keep the touch always cool. This is ideal for people with children at home!
