Heater was bought for child's room. It seems safe and works well. The comfort temp feature was slightly misleading due to the fact that we thought we could change the thermostat on that function. Instead you can use the number thermostat that goes from 0 to 5. I guess we thought we could set the temperature to a degree like 68. Other than that we like it and we feel that it is safe for our child's bedroom. We will see how it is on the electric bill this Winter.
