Review Content FIRE HAZARD I was paranoid regarding the fire starting potential of space heaters. I purchased the EV-HT20 because it is advertised as having an auto-shut off feature if tipped over. I tested this feature......the heater AND fan kept running after being placed horizontally. This product is good if your intent is to burn down your own house. Happy with purchase Bought heater for my brothers Christmas gift. He is very happy and warm as well Perfect office heater Perfect for office and ended up being a nice white noise machine. Similar model, lasted only 2 years... Worked well while it lasted. Whats the warranty??? mobile heater very easy unit to use and its quick to heat up a cold space ( enclosed) for comfort Keeps my small bathroom shower enjoyable It keeps my small bathroom warm for showering. Perfect for the coming winter months. So far, so good Given the mild fall weather, Ive only had occasion to use this heater several times. And I have yet to see how its usage affects my electric bill. But it does just what I-- a single man, living alone-- wanted it to do: heats me and my immediately area very nicely while I watch TV or read, without having to raise the thermostat setting for my entire house, thus burning expensive fuel oil. Its remote control is a cinch to operate. Ive refrained from giving it a five-star rating only because I dont yet know how much it costs to run.
