two of these required 15 minutes for installation.  Both are full after only 2 days of light rain...  Overflow works great...  These are thoughtfully designed.

I'm shocked how quickly two of these filled up in light rain from 1/2 my roof.  I want 4 more and am working on the boss for the go ahead.

I am extremely glad I purchased this vent for my trailer. It took me a while to work up the courage to cut through the roof. The last thing I would need is water pouring into my 6'x12' enclosed work trailer. But after a lot of research and youtube videos I gave it a shot. There actually wasn't anything out there that gave you an exact supply list and now I wish I would have made a video with clear instructions. I ended up making the wood framing for the ceiling of the trailer to go in between the roof supports out of 2"x2" lumber. My frame was roughly 14 1/4" across and 20" long (inside measurements). I had to add another piece of 2"x2" to make a square for the vent so the opening would be 14 1/4"x14 1/4" (again inside opening measurement). After constructing, centering and bolting it to the supports I was ready to cut the roof. I drilled a couple 1/2" holes in each corner and used my reciprocating saw to cut out the square using the framing as a guide. I talked with a lady at my local hardware store and she directed me to the correct caulk/adhesive to use for applications like this so it would be water tight. I covered the bottom side with whatever I bought and dropped it into place. I used an 8' ladder to get to the top of the roof and board to lean on so I wouldn't dent the roof... probably over kill. I attached it using self tapping stainless steal screws and applied more "caulk" to the tops of the screws. I then screwed on the bottom closure piece and that was it. It's been on for about 6 months now and not had a single leak... And we've had A LOT of rain in those 6 months. Would definitely recommend to anyone who has the right tools and is somewhat handy.

These car vent mounts are the best I've had yet! Unlike other vent mounts, you tighten the mount to the vent vs a spring snapping itself on the vent. I used to have a spring vent clip thing but over time it just wasn't as effective. However this one is so awesome I bought some for my coworkers and family!

Excellent boost for room at the end of trunk line. Rough guess it double airflow through that vent and keeps room cool as required and makes the room useful and comfortable. Bolting to rafters did make a little too much noise, so I mounted softly with bolts through heavy foam material, which seems to do the trick nicely. Installation was simple, and just a cut in the 6" flexible duct made for quick install with AC duct tape. Without a sensor, this unit stays on, and keeps airflow into that room continuous, but no worries about that at all.

Hardest part about installing this is getting up on the roof.  This is a great product and is much more sturdy than the OEM vent covers.  I would highly recommend that for those who have just bought an RV to buy these and replace the originals that come with your RV.  I also added on max air vent covers since I was up on the roof.

We've had this vent cover installed for about a month now, and it works great. As new full-time RV'ers we discovered that rain and wind were determining when we could take a shower (and vent the bathroom). This vent cover takes all the worry out of that issue. It allows the vent to work perfectly in rain or wind. The reason for 4 stars instead of 5 is because the cover only allows our vent to be opened about 1/3 of the way.  This is sufficient for our needs, but it's not what the vendor promises in their literature. Installation was easy and straightforward. Construction materials look great.

I was looking for a small, simple to install, vent for my storage shed to keep the shed from getting so hot and humid during the summer.  This vent fit the bill perfectly.  I installed it with a sealant and four self tapping screws in fifteen minutes.  Most of the time was spent cutting the hole in the siding.

I bought these for my dodge nitro, They way they fit inside the window channel is awesome. Best vent I have ever purchased. I will never buy vent from another manufacturer. They look like they installed from the factory, not an add on.

I liked the one I put in my mothers house some much,I bought one for mine. Her house(built in 1950) never had an outdoor vent and to install one would have been a tremendous pain,not to mention about 18 feet long with two ninetys. This awesome but pricey solution fixed the problem.

Great design built with a thick, quality steel. The flapper is much better than those at the big box stores. The thickness of the metal makes for a stronger, better vent for your dryer.

This vent is not airtight, but most dryer vents are not. The flapper is very light weight, and designed to easily move out of the way of the air flow. The way the vent is mounted will prevent dryer lint from accumulating on any hinge or piece of the flapper. Great design in that respect.

Note: For my bathroom vent application I also added a separate airtight damper in line with this vent to prevent backflow. For this application I was not worried about lint getting trapped on the separate airtight damper.  (http://www.amazon.com/gp/product/B000CDAFE6/ref=cm_cr_ryp_prd_ttl_sol_9)

I purchased two of these for a dryer and bathroom vent in a basement renovation project. I'm very satisfied with the quality for the price.

I recommend taping the seam of the vent pipe to prevent moisture from escaping the pipe into the wall cavity. Taping the OUTSIDE of the vent seam will prevent loose tape from blocking flow or causing a lint trap.

Installation in brick veneer:

Installation in brick was easy using a 4" core drill. ( Using this method as opposed to a lot of small holes drilled with a hammer drill bit results in a much more water tight installation, and water is the enemy of a home.)

1. With the 4" hole drilled FROM THE OUTSIDE, slide the vent in the hole to mark the screw holes.

2. After marking the screw holes take out the vent and drill the screw holes with the appropriate bit for your screw anchors.

3. Install the anchors for the screws.

4. Use metal duct tape to tape the OUTSIDE seam of the steel vent pipe which runs along the length of the vent pipe to the flapper end. Taping the outside will prevent a problem with a clogged vent if the tape comes loose in the future.

5. Put a generous amount of silicon caulking around the back, flat side of the vent before sliding it in a final time. Do not put too much close to the edge to prevent caulk from squeezing out when the unit is screwed tight. (Caulking the back helps seal the unit tight against the wall after screwing it in. The included screws appear stainless, but can always be changed out if they rust in the future.)

6. Screw the unit in place, being careful to not overtighten which can loosen anchors.

7. Use 100% silicon caulking on the top and sides of the unit, but not across the bottom. This way, if any water gets behind the unit in the future it can exit the bottom.

8. Celebrate your vent installation with the beverage of your choice!

Nice power Range vent hood that saved me money! saved about 150 vs ordering it at the box stores. Came all together and wrapped nice so no damage was done in the shipping process, It was pretty easy to install except having to get in the attic and run duct work.  Wish the lights were LED and in the front as these are in the back. How-ever, others I found were more costly and this one and I have gotten many compliments

This is my third one so obviously it works well. If you buy it with the roof vent from the same manufacturer, it screws in through a slot and simplifies the installation.

Easy on/easy off the air vent for when I'm traveling.

I found this vent after looking for something to stop the draft that was keeping the laundry area off my kitchen so chilly. Have been using it for over a month now, in sub freezing temperatures, and have really noticed a difference in the temperature of my living space. It is not as big and bulky looking as some reviewers mention and was very easy to install. Wish I had found this years ago!

I love this air vent mount for my GPS. It works great for me. My vents are in a good place so I can see the GPS really well. Might not work in cars where driver's side vent is real close to the steering wheel, but this works great for me. At this price, I'd be willing to try it!

I bought these vent shades for my 2015 Dodge Journey because when we purchases the vehicle it did not have them on it. These fit so perfectly and make my windows look so much better. I love that I can get some fresh air while it's raining and I'm driving. I love how easy these were to install on my windows. It came with all four for the front passenger and driver windows and one for each side in the middle.
