   This item looks a lot bigger in the picture. It does give decent heat for its size and it is pretty quiet. I feel like it blows better at a low fan speed but all in all this was really easy to hook up and I’m happy with my purchase.

   I had to tape up 1 side of my blower to reduce the CFM as the blower was just cooling down the heater. You have to be with in a foot or two to actually feel the warmth anything past that its cold air blowing. But its enough to thaw out my feet and hands in the morning.

   Great for the price, and up close it’s great for heat, but more than 5 or 6 ft a way and it feels cold again. For that reason it’s a 3 star product

   These fans are great when they work but only hold up for 3-4 months before they die. I even had one come that was broken out of the box. Overall I like the fan heater combo for size and overall air movement, I just wish they used better components as I’m actively searching for a better solution. Once found, I won’t be purchasing any more of these.

   I’ll update if the shop gets to be colder than 60 degrees. If you are not within two feet of it it feels like it’s blowing cold air at you. It’s good for warming up hands. I tested the heating. I put a piece of cardboard in front of a tested the heat before and after turning is heater on and it made a 17 degrees difference. Again this might be different when it’s actually colder outside. I will update. So far I’m neutral on this product.

   The Heater Attachment, Works good, Although if you turn up the fan motor to high it cools the heat made by the attachment coil down to cool again, Which is good in a way,,… all that is saying that is the barrel fan blower is very strong the volume it puts out the small unit is amazing …. so put your hand in front of the blower wind it is delivering to best fit your needs…. i leave it on THE lowest setting and it blows more then enuff HOT air then need be,, the 20×20 room came to temp’ very fast with in 20 or less you take notice of the radiant heat the small blower puts out, You can also test your unit to see if your attachment can with stand higher blower volume for your use and demand of your cold enviroment cituation.. That your currently warming at the time of need…. Then adjust it accordenly… REMEMBER: when done breaking the chill in the room, slow it down accordingly …making it to hot in the single room is not good for you or others, It will be warming fast dont leave alone, The unit blower or attachment wont get hot to the touch but’ the Free flowing air you are heating up will be over whelming before you realize it… Also: when you break the chill in the room turn it down to the lowest setting and it will maintain the temp you desire just crack a door open or small vent or window very small vent opening will keep the warm air fresh meaning you wont start sweating if the air flow is circulating or escaping slightly.If the air flow out of the unit is blowing to high you can put something under the back legs or What i did is Turn it upside down with the blower outlet was flat on the floor and it heated from the floor up in stead of from the unit pointing up and the cold was concentrated on the floor or lower half of the room…. You also can use this unit in a vehicle just get an adapter from amazon or your local general store from a cigerette lighter power out port DC to a AC appliance or unit … works fast to clear a windshield or defrost a motor block so it will start in the mornings a lot easier …. This little unit is very impressive your getting your moneys worth times two … the casing is very thick and it wont hold heat ….meaning no matter how long you had it on you can still touch it without gloves if you had too…by picking it up and moving it.. Its great for outside pets or working on a vehicle in the cold in the dark. Meaning the cord os very long so you can drag it around to the whole room if you need to reposition it for others needing the high volume heated air…. BUY ONE OR TWO today… you wont have any problems with the endurance of this product.

   I bought this not expecting it to heat my area up but I atleast expected it to heat up to a few feet away. I use it for a hand warmer when I come inside from the cold. Have to put your hands right on the heater to feel anything.

   The media could not be loaded.  Sounds like an air compressor!
