A very good heater ar a great price. My issue  with it is, I don't  see any safety  precautions.  For instance, it don't shut off if it's move or fall over, it gets very hot on the outside,and the top is vented and gets very hot.I am afraid  to use it.Afraid to donate  it as someone's  house could catch a fire,will be throwing  it out as soon as my other one  arrives.......Too dangerous
