Item works pretty well, of course it's a fan that pushes air, how hard is that to achieve? Most problems pushing air from one room to the next have to do with ventilation in general. That is, if you're pushing air into a room and you close the door in that room, with thick carpet, there's no way for the air to escape the room so your fan isn't going to work.
This suncourt unit is nice in that it's sound level, even on high, is relatively low. But one other benefit is that it has a variable speed dial which allows you to, effectively, turn down the volume. Most fans settings consist of either a high, which is obnoxiously loud, or a low which doesn't push any air. So this fan pretty much takes care of that issue.
I used it on top of a standard 4" x 12" floor 'register' by just using 3 pieces of 12"x12" (2" thick) foam pads purchased at a hardware store. I took off the register grill. Cut the 4" x 11" center out of the the bottom one to go over the duct opening. Then cut the top two out with the enclosed 'wall' template cut-out included with the fan. The foam helps insulate the sound and doesn't seem to affect the airflow any. You do have to make a 'plug-in' end for the fan as it only comes with a 'pig tail'. So get a $6 extension cord end at the hardware store as well if you plan to plug it in to a wall outlet. It's not glamorous but it works pretty well and I believe it moves far more air than a standard register (insert) booster. Not to mention, the 'grill' you see in the picture can be rotated 360 degrees to direct the air in any direction you want.
I'll try to include a picture of my install in the user photos in a day or two.

I have lived in the home I am in for over 14 years and have always had a problem in the winter with getting heat from the wood stove into the back bedroom. With this through the wall fan it has increased the temperature by about 5 to 7 degrees. It was worth the price for the extra comfort.

I own a pellet stove that I have in the basement. I was leaving the door to the cellar open and letting nature bring the heat up. Sometimes the room in the cellar was 80 degrees or more. With this fan mounted at the top of the stairs and exiting into the living room I am getting the heat where I need it and the cellar is cooler. It's a win win. I was having trouble with the fan initially and sent it back for a replacement. I again had problems and worked with the company to figure it all out. They were very patient and I found the problem was mine, not theirs. The fan works as advertised, maybe even better. I encourage anyone that needs to move air from one space to another to purchase this product.
Honest reviews on Thru-Wall Room to Room Fan
11/28/11 We use a woodstove to heat the house in the winter. The room adjacent to the living room was always cold so we looked for a way to move warm air from the living room to the adjacent bedroom. I researched several fans and this one fit our needs because we specifically wanted a minimum of 100cf of air per minute not be limited to just 100cf per minute. The Amazon price was the lowest.
The Amazon website for this fan is lacking in the technical information we needed to make an informed purchase so I had to go to the manufacturer's website. This fan moves 100cf (low) up to 200cf (high) of air per minute using an adjustable speed "knob" on the front of the fan and it was supposed to be pretty quiet. It also has a rotating grill to direct air flow which is convenient. Some of the other websites offer the fan without the rotating grill at a lower price. I'd never consider that option because we want to be able to direct the airflow as needed.
The installation was not difficult. I recommend getting the wax tracing paper found in the sewing department of a fabric store or something similar to transfer the template outline to the wall. It makes it easier to cut the sheetrock without having to mess with the paper template getting in the way. You can cut it with the template, just make sure you securely tape it to the wall (use blue tape not duct tape).
We put the fan about 4' from the corner and 6" from the ceiling on the wall nearest the woodstove. It's in a great place to capture the heat and move it to the next room.
It helps my husband is an electrical engineer so he was able to do all the electrical work. He put a light switch (the flat decorative kind, not the regular toggle kind) on the wall below the intake side of the fan. This allows us to turn the fan on and off from the living room where the woodstove is located because we don't need to change the fan speed.
Also, having the switch on the output side room would have been inconvenient for us (and probably not necessary since the on/off speed control is on that side of the wall). Besides wanting to control the heat transfer from the room with the heat, every now and then some evil smoke sneaks out while I'm reloading wood. I don't have to run around to the other room to cut off the fan while I'm trying to get the air purifier turned on to get the smoke out of the room.
We did put insulation in the wall around the fan (as suggested by another reviewer). I don't know if it helped; however, we had the insulation so it wasn't a big deal to use it.
I said earlier the output of this fan is 100cf to 200cf. The adjustment knob allows for very minute adjustments to the fan speed. This is important because you need to find that sweet spot between air flow and fan noise. This is an inexpensive fan and even though the paperwork says the fan is balanced, our fan makes more noise as the speed increases. It wobbles on high speed; however, that doesn't concern us because we would never use high speed. Wobbling on the higher speeds is the only reason I gave the fan four stars instead of five.
I can't find a way to import a picture or you'd be able to see one of the nice features of this fan is it's pretty discrete on the input wall. We have it high enough on the wall so it's functional yet out of the way. Both sides of the fan can be painted I'd recommend you do it before your final installation so you don't have to mess with taking it down and putting it back up.
Overall, we're pleased with this fan. The temperature in the adjacent room is significantly warmer and the minimal fan noise doesn't bother us at night.
ETA: 12/13/11 I changed the stars from four to five. This fan does a very good job for the price. I now have the fan speed halfway between 100cf/minute and 200cf/minute and the sound is barely discernable unless you're standing right under it. The reality of it is there's all that power in that small housing so it's going to make some noise. However, my ceiling fan on high makes more noise than the wall fan. We've had it in the wall for a couple of weeks and have been pleased with its ability to push enough air into the next room to keep it at a comfortable temperature.
ETA: 12/27/12 It's been a little over a year since we installed the fan and I am so glad we did it! Right now the outside temperature is 26 degrees and we're nice and warm in the rooms that get direct heat from the wood stove and I can walk into the bedroom and not get slapped in the face with cold temperatures (as I did "before fan").
The bedroom will never be as warm as the rooms that get the direct heat and that is fine with us because we want the bedroom to be a little cooler when we sleep. That being said, this fan does a very good job at keeping the bedroom significantly more comfortable in cold weather. The switch we installed on the wall has been a convenient feature and I recommend anyone installing this fan also put in an on/off switch.
I still can't figure out how to put a picture in this review so I could show you the location of the fan in relation to the wood stove and also where we put the switch so I'll try to describe our setup.
We have the wood stove at an angle in a corner in the living room. The fan is on the adjacent bedroom wall straight up from the stove (about 5' from the top of the stove to the fan we have low ceilings so the fan is about 6" from the ceiling). The on/off switch is on the stove side of the wall about 4' from the floor and over about a foot from the stove so I can easily get to it and the heat from the stove doesn't affect it.
We chose to put the on/off switch on the stove side of the wall because that was the most logical place for us to control the fan. There have been a few times I've let smoke out of the stove when I added more wood and it was easy to reach up and turn off the fan so the smoke wouldn't blow in the bedroom. I keep a Holmes air purifier in the living room so I can turn it on when I have "duh" moments such as that. Thank goodness those times are not as frequent as they were when we first got the stove all those years ago.
My husband and I were talking a few days ago about how much we liked the fan and why did it take us so long to get one. I reminded him of all the research we did in years prior to buying this fan and just couldn't find a "good" fan. We didn't want to cut a hole in the wall and then find out we made a mistake.
Then I found this fan on Amazon and did more research and we've been very happy with it. I cannot speak to other people's experiences; however, for us this fan was an excellent choice.

we have two small rooms off our bedroom, a walk-in closet and an office, and neither has heating or cooling. installed this fan between them to create circulation and it works great, pulling heated or cooled air into one room, through the wall to the other, and pushing it back out into the bedroom. adjustable speed is nice. gave it 3 stars because would be nice if the fan was a bit quieter at high speed.
