I keep this to heat my bedroom. My windows are not properly insulated. I have had this unit for a week and use it every night. It runs slightly loud when im trying to sleep but it's no different from an air conditioning unit in the summer time. It has a slight burning smell when you first run it but it goes away within minutes. Overall, I'm very happy for buying this unit. For the price, it does a great job keeping my room warm all night while I sleep.
The first time this heater was plugged in it sparked and smoked and the fan would not turn on. Returned ASAP I considered it a fire hazard.
I unpacked it from the new packaging and plugged it in but it didn���t turn in. Didn���t work at all
It is a good heater. I would prefer that it be manufactured anywhere BUT in China.
