Rated 4.0 out of 5.0 by Dallasite seems to work as described
so far they seem to work as described. I have purchased 4 of these. my old house had two dormer vents that were 22x22 inches and they did a great job. The square passive vents on my new house didn't seem to work at all. I needed something that was close to the HOA standards so I searched until I found these round short vents. I put a thermometer in the attic to measure temperatures. My attic would run from 130-140 on a 100 degree day in dallas. I also purchased solar panels and dc fans to pump out heat during the day. This did not work at all on the square passive vents. Not hardly any air would pass through the vents even with the fan running fast. The old vents were about 10x12" holes in the roof. I added these round Aura vents (I increased the hole to 12x12") and there was a difference in the attic temperature by about 7-8 degrees. However, I didn't get them in until it started getting cooler, so they may do a better job than this during the real hot days. I also, have not added the solar panels and fans to the setup yet, to determine how well it has made a difference on its own. Looking at the design it seems it might leak. But like other reviewers, I have gone up during a couple thunderstorms and only have some condensation on the underside of the vents. I don't find them leaking at all. I consider myself a shade tree handyman. Hope this helps you.

Very happy with the craftsmanship of this product. Only wish that home depot carried the models with taller collars.

Have tried a number of things this summer to lower the attic temperature and the living space temperature above the 2nd floor bedrooms in my home. Added more insulation and radiant barrier, duct boosters on floor registers to improve airflow, etc. Calculated that I had enough attic ventilation between soffit vent intakes and static roof vent exhausts and checked that all vents, especially the soffit vents were clear of insulation, debris, etc.
After installing radiant barrier, placed a wireless thermometer in my upper attic and recorded a peak reading of 129 degrees on a 95 degree sunny July day in the Midwest. Had another thermometer in the second floor hallway that had peaked at about 86.5 degrees. Believe it or not, this was an improvement of about 2 degrees prior to installing the radiant barrier and duct boosters. Also used an infrared thermometer to check temperature at attic intake and exhaust vents outside and did not get the sense that hot air was properly exhausting through the roof vents (standard box vents).
Looked at power venting options, but decided the initial cost, ongoing power costs, and poor life expectancy of powered exhaust fans was not the best option. Read several positive testimonials of aura vents from what I considered reputable sources and decided to give the a try. I especially liked the low maintenance, no moving parts design, and felt, where I live at least, wind is more consistently available than solar for moving air through vents on my roof.
The Home Depot price and shipping was much better than from manufacturer though was concerned that my steeper roof pitch might pose a leak risk. Manufacturer claims to have a modification to prevent leaks on steeper pitched roofs, though Home Depot website says this unit can be mounted on roofs up to 12/12 pitch. Units have a solid aluminum plate around the top half of the back third of the louvers (the part pointing highest towards the peak of the roof). Should be okay for rain, but we'll see when some 6-8 inch snowfalls come this winter. The weathered wood finish is reasonably close to the standard timberline asphalt shingle weathered wood color.
Installed two 12 inch aura vents in place of 2 static box vents near the peak of my roof. Next day was another 95 degree day nearly identical to the day in July mentioned earlier, with a slight breeze. Placed the wireless thermometer back in the attic and never broke 116 degrees--so 13 degrees cooler in the attic than the 95 degree day in July and this time peaked at 84.3 degrees in the second floor hallway for another 2 degree drop.
There seems to be some debate about what is a reasonable target for attic - outside temp differential. Some say they should be nearly equal while others suggest a 10-20 degree differential is okay and expected. I'm curious to know if additional vents will lower my attic temp further and lower the inside living space temp as well or if that would just result in diminishing returns and worth the extra cost and effort.
I have a few more things to try, though am happy with this result from just adding these 2 vents. May consider more similar vents on other parts of roof, but need Home Depot to carry the modified version with the full (not half) covered plate on the back third of the vent to prevent water leakage on highly pitched roofs. The manufacturer charges excessive shipping (nearly as much as the vent itself) which makes it cost prohibitive and I will have to keep looking to get them somewhere else for a reasonable total price (vent + shipping charge).
Sorry for all the detail--thought I would give the kind of review I would like to find when I research products.
Overall, happy with the product and to see Home Depot carrying it. Would like to see expanded options for greater collar height, vent diameter size, and highly pitched roofs.
