Rated 3.0 out of 5.0 by Hotmomma I'm not sure yet
The unit is pretty quiet, but I'm not sure that my room is any cooler.

Rated 1.0 out of 5.0 by Dmbterp898 It worked, but plan on bringing it back
Let me start by saying that adding a fan to my upstairs vent noticeably cooled off the entire upstairs of my house. So I know the idea works; however, this product was very noisy.
The fan has a mild hum when running, that is not the problem. When the fan turns on and off it has a plastic on plastic scratching sound that is unbearable. Not sure if it defective or just part of the design, but I plan on bringing it back and looking for an alternative model/style.

I am currently pregnant and going through a 100 degree plus summer in California. I was convinced my husband and I were going to have to have our AC system redone just so I could survive the summer. I was so hot and miserable. In a last ditch effort, we came across this and decided to give it a try before paying thousands to redo our AC. We've had it for about 3 months and it works AMAZING! Just put in whatever room upstairs that is super hot, for us - our master bedroom. Makes about a 5-7 degree difference. The master bedroom is still warmer than downstairs, but nothing like what it was before. I have recommended to multiple people who have the same issue with upstairs being hotter than downstairs. Also incredibly simple to install and automatically turns on when the AC does.

Rated 5.0 out of 5.0 by Paul Mounting it is a little tricky on a wall register, but it does help move a bit more air.
It works fine on floor registers. You have to mount it on wall registers and that is a little tricky. But they include an excellent template to help drill the hole for the screws. It seems a little noisy, but it only runs when the air blower is running, if you set the controls correctly.

Rated 5.0 out of 5.0 by jmacncincy Helps considerably in older home
We bought two of these for the upstairs bedrooms in our cape cod nearly 10 years ago since there aren't any cold air returns upstairs. They have really helped in terms of helping to force cool air into the rooms in the summer. Before we had our house reinsulated, we used it in the winter as well. Overall they have been a lifesaver for our situation.

After recently installing an A/C system in my older home I quickly realized that the upstairs registers weren't putting out enough air to adequately cool the area. The vents were just too far down the pipe and there was apparently too much leakage much along the way despite closing off all the downstairs vents. Thought I'd give one of these a try. Well, turned out that it was terrific - seemed to more than double the volume of cold air coming out of the register and immediately lowered the temp in a problem area by at least 5 degrees.
Appears that this is exactly what was needed to solve my problem and get the cool air flowing into the area where it's most needed. Fact is - I plan to head back down to the local store and pick up a couple more later today - love this product.

Rated 2.0 out of 5.0 by mholdr not powerful enough....returned it
didn't increase airflow at all - the fan is not powerful enough to draw more air thru the register. Ended up returning it. As others have said simply removing the actual vent/register provides more airflow. Oh well, I gave this thing a shot and it didn't work.
