The Lasco 5812 is a very good heater especially since it has stronger fan forced air than any other I have tried & still not loud, even stronger air flow than one costing over $90. It sends the air along the floor rather than out of the top. Moving warm air can be felt for at least 5 feet from the heater. I measured it. One serious drawback is that the thermostat even though it controls the heating of the air from a lower level of 750 watts to a high of 1500 watts, it will not cut the heater off when the thermostat setting is reached. It will only lower it to the 750 watt maintenance level. This is not a problem if the heater is located where you can turn it off yourself when the room is warm enough or the temp is too cold for it to need to shut off. Where I find a problem is in my office which is unattended for hours at a time and over night or I am away on a trip. I like to keep my computer, etc. at least 60 degrees when I am not around. Since the outside temp varies from night to day which affects the inside temp, this heater will stay on even when warm enough although it will lower to the low wattage. This means that my office could get a lot hotter than desired during the day when unattended. Because of this, I use the more expensive $90+ heater in my office even though it seems not to put out as much warm air and certainly not as strong an air flow as the Lasco 5812. The Lasco works as designed very nicely, but uses electricity even when not necessary. To be just about perfect, all it needs is a thermostat that will turn it off rather than just provide controlled high and low heat. It is great when you will be around to shut it off yourself if the temp over reaches your desired amount like in your den while watching TV. I like mine regardless. Besides, the company does not want you to leave the heater unattended for safety sake anyway...Dan

The build quality is great, but it is louder than most heaters and the thermostat will never shut off the heating element even at the lowest setting. The noise isn't outrageous, but it's definitely on the loud side compared to other forced-air heaters I've used. As for the thermostat, this probably wouldn't be a problem on a very cold night or in a large room. In my small room on a mildly chilly night, however, the heater remains on even when the dial is on the lowest setting. I was roasting. Too bad. The build quality seems really solid, and it comes with a three-year warrantee.

Great Little heater, good Build Quality, unit won't shut off when at set temp . It's just a simple good little heater. It has a thermostat control, power switch, auto shut off if tipped, and forces are from the top and hot air forced to the bottom so you can place the heater against the wall if needed
Honest reviews on Lasko 5812 Automatic Air-Flow Heater with Temperature-Regulation
I bought this space heater in October of 2008 from a vendor on Amazon.com. I'd gone back to school and was renting a basement apartment with little heat. This heater made the late autumn/early winter of Michigan's Upper Peninsula bearable, and my small room livable.
It's been going strong in Mid-Michigan, all through the night, in front of the front the door, for over two years. I place it there at night and it really mitigates the chilly air that comes off the steel door. The fact that the hot air comes out the bottom makes my cats happy and my feet, too. Now, winters here can get down to -30 deg F, and if the wind's blowing over 10-15 MPH, even colder. Late 1970's trailer homes aren't known for being well-insulated and this really helps keep the propane bill down by making the room I'm in warm and comfortable.
If I turn it past midway, the poor heater turns itself off and has to sit for about 45 minutes until I can turn it back on, but it can run through the night, 8 to 9 hours, on the lowest (750 W) setting or just slightly higher. It's blowing warm/hot air, so it's not silent, but it's a white noise so it's very easy to ignore. If you want to use the highest setting, use if for only 40-45 minutes or it will turn itself automatically. I think there's a fuse that overheats at that setting.
It has a very heavy cord, which makes it ideal if you need to step over it or tug on it inadvertently. It's not fancy, but it got me through three days of no propane during a cold spell of 10 deg F during the day and -20 deg F at night. It's been kicked, pushed over, had cats run into it, had groceries dropped on it, and it still does what I purchased it for: it keeps me warm, supplements my furnace so I'm only heating the room I'm in and not the whole trailer, and it keeps the cold drafts from my feet.
I was actually thinking of buying another one because of both its toughness and its decent cost. Well, if this one does quit working, I will most definitely replace it. It's not perfect, it's not pretty, but it does the job it's built for, and if I could, I'd give it four-and-a-half stars.
UPDATE:
This heater lasted three and a half years, giving up the ghost in January of 2013 after three power outages and two subsequent surges. I will definitely be purchasing another one. This heater was both durable and effective.

I just received this heater today. The problem is that the heat never shuts off, becuse the thermostat controls only the variation between 1500 watts and 750 watts. Even at the lowest possible thermostat setting the heat elements will never shut off. If you have a large, cold room it's fine, but if you're trying to heat a small room, such as a bathroom, or using it to supplement a heater in a larger room, the heat will keep on building and building up without control. Obviously, in a bedroom situation you would have to get up at night to manually adjust the heater--turn it off--then get up later to turn it back on. This is not a heater that can be used without constnt supervision and manual adjustment.
I called customer service to find out if this is a design flaw, or am I missing something, but have not received a call back. Rereading some of the reviews of this heater, I notice that some people mentioned this design flaw, but it was not stated vehemently enough to disuade me from buying the heater. I am bluntly stating it now; this is an enormous problem.
