We have one of these heaters in our kids' room and have had it there for about three years. They're on the lower level of the house, which is especially cool in the winter months. Rather than heat up a big part of the basement, we opted for this space heater. It is a little hard to adjust the temperature, as you have to push one button repeatedly to get it to your desired setting. I found out after using it for several months that to turn it off you simply have to depress the button for a few seconds, rather than pushing it several times to scroll through all the settings. The fan run quietly, and the heater turns itself off once the room gets to the desired temperature. Safety UPDATE: When our room was very quiet, I heard a strange humming noise and discovered it coming from this heater. I went to unplug it and the plug was very warm. I know you're not supposed to leave space heaters in, but in the case you forget this didn't seem very safe to me.
