    CLAUDIA -- lynchburg, VA   7/21/2014
    This product is 6 x 12 and my vent is 7 x 13. I thought I could rig a flange around it make it fit, but alas I could not. No pre-made flange available from Smarthome. I can not rate it since I didn't even plug it in. Wish they made this in a 7 x 13 size. Rating it 3 stars but it probably works great - I just dont' know.
    SHERRIEBELLE -- rochester, MN   4/24/2014
    this was a replacement for one that finally wore out after 10 yrs of constant use. The product does exactly what it needs to do boosting the air from not enough vents in the sunroom.
    CHRISTINE -- sussex, NJ   4/3/2014
    Good product - arrived in timely manner.
    DAVID -- elizabeth city, NC   8/19/2012
    This is a great product. Our summer has been exceptionally hot this year. We ordered 5 units. We can really tell a temperature difference in the rooms with the boosters. We are very pleased with them. The only downside is that they are a little loud but the cooler rooms are worth a little noise!
    RICHARD -- tiffin, OH   8/5/2012
    The booster fans work great. They are used on our second floor bedrooms, and they help to boost the cool air up to that area of the house very well. All the upstairs rooms are noticeably cooler now.
    KATHLEEN -- leesburg, VA   8/2/2012
    These are easy to install and easy to use. They do boost the cool air coming from the vents. I wish they came higher off the ground with more open area on top. Other than that, I would purchase again.
    PATRICK -- claremore, OK   6/4/2012
    Well, it is easy to adjust to kick on and off automatically...... But I put a thermometer in the room and monitored it since the day I placed my order, and after I received my order. Only .4 - .7 degree change. It is the only room downstairs that isn't covered by the second floor of my home, but well insulated etc..... Didn't really seem to help at all.
    JAMES -- stillwater, MN   2/9/2012
    Unit works as described, a bit of noise but manageable. Air volume is acceptable, in all it works as required to boost a weak duct run.
    WAYNE T. -- high bridge, NJ   1/27/2012
    Slightly noisy, but it really helps move the heat from the end of the longest run from the air handler. I suspect it will be even more valuable in AC season , since in the room we spend the most time in, the vents are on the floor (hey, I bought the house, I didn't build it!) As a benefit, it's easy to tell when the heat is running.
    Ed.Grossett -- Windsor Ontario Canada   12/14/2011
    This booster fan works just great, it has saved me a lot of tearing out and rebuilding, what a great product!
    DIANE E -- opal, SD   11/16/2011
    so far they seem great glad I bought them
    HARRY -- georgetown, MA   10/20/2011
    Working great! Does exactly what it's supposed to do
    MARYANN -- cicero,, IL   9/1/2011
    I have been looking for something to help cool off my upstairs for years & now I found it. Right now I am using it in my computer room & I am completely happy. It helps cool enough so that my computer hasn't been overheating and I can stay on it longer . I am very happy that I bought this booster fan and that my neighbor told me about it. I am hopeing to buy more.
    MARTIN -- north platte, NE   8/22/2011
    These seem to work as advertised. However cool air output from the vents has not increased significantly.
    PHILIP -- arden hills, MN   8/21/2011
    I tried it in a room that faces East and can be 5 - 10 degrees warmer that other rooms upstairs. It did not help one bit. Tried it on both the register and the return register.
    CHARLES -- tucson, AZ   8/14/2011
    These units do work as advertized but there is no way to power them from the ducts.
    KRIS -- tacoma, WA   8/13/2011
    We ordered 2 booster fans. One of them comes on with our air conditioner and the other stays on most of the time(no matter what the setting is). They do seem to produce exellent air flow - the difference is really noticeable.
    PRISCILLA -- holiday, FL   7/14/2011
    the booster is excellent. it was easy to install and the cost of the unit was very reasonable in price. we are using with the a/c. have to wait for much colder days in our winter season. but so far so good. very happy.
    ZENON -- voorhees, NJ   7/14/2011
    We had this product for @ three months (may/june/july).Works well to help lower temps in our upstairs bedrooms during hot summer days and especially nights. Fan is a bit loud and thermostat, when triggered by cool air turns fan on for few seconds then stops fan for about 15 seconds and then fan goes on and stays on til a/c shuts off. This is something we got used to and doesn't bother us. Upstairs living and especially sleeping has been much more comfortable since we purchased this product making it, overall well worth it. Five stars if fan was quieter and if it had no thermostat glitch.
    GEORGE -- medina, OH   7/10/2011
    Very easy to install and works great. Before my second floor bedroom was three degrees warmer. Now it is the same temperature as long as I close the door. We are going to get another one for the second bedroom.
