I've tried several types of electric space heaters - radiant heater with resistive wire ribbon, oil-filled radiator, quartz, and now this. This is by far the best. The ribbon and quartz heaters glowed bright orange, lighting up the entire room. The Sunbeam/Holmes quartz tower heater made a rattling noise from the heating elements and also had a fan which was really loud and quite startling when half asleep. I nearly had a heart attack when it came on a couple of times when I was half asleep. It lasted less than 2 seasons due to an unbelievably primitive thermostat which stuttered and turned on/off every few seconds for as long as a few minutes before it stuck in either the on or off mode. The oil filled heater worked OK for a few years until the heat broke the perimeter weld and it began to leak oil on the floor. This heater is absolutely fantastic so far. It's not absolutely silent like an oil-filled radiator. You can hear a very quiet hum which sounds like a transformer when the thermostat turns the heater on. You only hear it at night when everything is absolutely silent in the room, and it's barely audible. The hum is louder on the high setting, but still quiet. The unit heats up fully within a minute or two and heats up a room as fast as any other type of space heater. It emits no light. The heating element appears to be a heavy paper or fabric sheet which is suspended in the middle of the housing. There's no fan. The upper knob is the off/low/high switch. The lower knob is the thermostat, which reads 1 through 6. I only use it on the low setting with the thermostat set at 2. It heats up a 250 sq. ft. room with a 10-foot ceiling like nothing when it's 40 degrees F outside. It has a recess on the back side in the middle of the upper edge which serves as a handle. It's very light and can be moved very easily by lifting. It has 4 rollers for feet which not only makes it easy to roll around, but keeps it from tipping over if it's bumped, since it will roll out of the way instead of tipping over. It has a tip-over switch which turns it off if it's tilted too much, not that it ever gets hot enough to ignite anything. The tip-over switch makes a rattling noise like something is loose inside if you shake the heater - it's not a broken part inside. Unlike an oil-filled radiator heater, it only emits heat from one side which allows you to move it out of the way and use it without fear of heating whatever is behind it. The back side is so cool that it comes with a plastic bracket which allows you to hang the heater on a wall. So far this heater is fantastic. I've used it for one season without any issues. I recently bought 2 more and to see if they will allow me to stop using propane central heat altogether. I placed two of them in the living room, plugged them both in and set them to full blast. 10 minutes later, they tripped the living room breaker, so I tried one on full blast for a couple of hours. It took 2 hours to go from 60 degrees to 62 degrees inside. It's obvious that one isn't powerful enough to heat most of the house, and going by the paltry increase in temperature, I'm now sure 2 of them wouldn't cut it either. These work great in a closed bedroom to heat up the whole room. If using on in a large space like a living room, it'll only warm people who are close enough to feel the warmth coming off of it. UPDATE 8/25/2017: I've discovered that this heater is causing me problems. During the night and especially in the morning my heart rate is elevated, my heart is pounding hard, I feel jittery and nervous and my body is vibrating. I seem to be sensitive to electromagnetic radiation or something that this unit is giving off. If you don't experience these issues, this is a great heater.
