Rated 4.2 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by I was surprised at the speed of delivery! I am completely happy with the ease of install and the thoroughness of instructions.Two hours from start to finish.My attic in the hot New Mexico sun went from 160 degrees to 92 degrees in three hours and has not been above 95 degrees since.My recommendation is if you do not have one get one!

Rated 4.0 out of 5.0 by Pretty Effective Moves a lot of hot air out of the attic on sunny days, however, even a few clouds slow the unit way down, nearly to a stop, moving no air. Overall, our A/C unit does run less in the summer, which was the reason for the purchase. Noticably cooler in the attic as well. September 6, 2011
Rated 4.0 out of 5.0 by solar attic power vent This product is great, not so much for 1800 sq ft as advertised, but install two and combine the solar panels for increased efficiency, and it dropped the temp in my 2100 sq ft attic by 40*f. Well worth the purchase price as the cost is better than other distributors. Delivery was quoted 5-7 days, I received in two!!! September 20, 2011
Rated 5.0 out of 5.0 by Overall a great product I was a little concerned initially when I opened the box as the unit seemed sorta flimsy...the hood mounts didn't seem adequate to hold the weight of the hood and the hood mounted solar panel. Once it was all installed, it was fine and seems to be withstanding the weather, wind, etc. I had a roofing company install the until while putting on a new roof. It only took them minutes to cut the hole in the roof and mount the unit. I can see how it would take a bit longer to install on an existing roof, but still seems very do-able for a do-it-yourselfer. I connected the solar panel and ran the power cord to the fan motor. Very straight forward. The unit works really well with direct sun. The amount of air it pulls is surprising for a solar powered unit. It even works with clouds.... albeit the fan motor runs slower, but it's still pulling warm air out. The motor runs very quiet and it can't be heard...even when just a few feet away while on the roof next to the unit. All in all, I'm happy with my purchase and would recommend this product to others.

Rated 3.0 out of 5.0 by design & execution lackluster We needed two fans for our roof, and possibly more for another building so bought a 25-watt fan from Home Depot but another manufacturer, and this Ventamatic 12.6W in order to compare. In general there was lack of quality in design and assembly of the Ventamatic. First, there were no signs of damage to outer shipping or inner cartons, yet out of the box, when rotating one of the fan blades hit the surrounding cylinder. We moved the outer end of one of the struts or supports so that the cylinder could return to round. This was careless positioning when assembled but it should not have shipped with such an obvious defect. An assembly jig would prevent this defect. Second, the welded wire cage beneath the dome, to keep out birds and bugs and sparks, was a good 1" short of covering the gap because of the way it rests on the supports. Design problem? Wire cage cut too short? Skimping on materials? Third, the plate bars intended to hold the solar panel at an angle are ill-designed. The ends are cut at right angles but need to fit into what is a long narrow trapezoid between the horizontal base and the tilted panel. There are many combinations of upper and lower bolt holes simply impossible to use because the corners of the bars force the hole in the bar above the hole in the base. Did anyone even try this? The user will need to either drill new holes into the bars, base or both, or trim the corners of the bars to bevel, or substitute other supports. Fourth, unfinished sheet metal edges make it unpleasant to work with. The dome itself has a rolled edge but nothing else was rolled or ground after being cut. Presumably the unit is only handled once or twice in its life so I understand the lack of finish but overall impression is of careless design and execution. We could have returned the unit for the first defect but the other three are inherent. And we had the holes in the roof, the tools and weather to proceed. EXCEPT the quality of the crystals on the solar panel was a bit better than on the other model. A caution: we did not understand from the web page that the wiring between the panel and the motor MUST run through a separate hole in the roof. There is no provision to run it up through the unit, even when placing the panel directly on the dome. In operation the Ventamatic "warbles", is higher pitched and I can hear it three rooms away. The other model is more quiet; I can hear that it is on but it does not draw attention. In the mornings, for about twenty minutes the fans can cycle on and off as the temperature bounces around, at least that is our hypothesis. Another dollar in thermostat electronics could add a better threshold? In the evenings the fan cuts off due to sundown even though the thermostat is still calling for power and we do not notice the cycling. p.s. I have tried two computers, three browsers to upload a photo but always times out. June 10, 2014
Rated 5.0 out of 5.0 by Good Product I own a home repair business, and have installed this unit on my house (actually installed three on my house) and customers'. I like the fact that the solar panel is adjustable, so you can aim it in the direction desired. And yes, it will not work without sunlight. Even cloud cover will not allow enough light to power the solar panel, but that's OK, because we are concerned about radiant heat. May 11, 2012
Rated 5.0 out of 5.0 by Cooled my attic off very well I have a single story 1950 sq foot home with a large attic. Apparently when my roof was replaced a few years ago no vents (other than the soffit vent) were installed. My attic normally would be like a sauna during the summer months (I'm in Austin, Texas). After having two of these installed, on opposite slopes of the roof, my attic at 4:00pm is just WARM. It's significantly cooler than it used to be. I can actually breath while up there and it doesn't feel unbearable. August 21, 2012
Rated 4.0 out of 5.0 by So Far So Good, Creative install to vent a cathedral ceiling. So far so good. Also wired it to a manual overide switch to keep it from running in the winter. October 24, 2011
