Morpheus171: I like the prospect of keeping vermin out of the dryer vent. This is my second purchase. The first one lasted 4 years until the harsh winters took a toll on the plastic. But other plastic items have been ravaged by sub-zero temps. as well. Painted it to match the other house fixtures. Might want to have some sealing caulk or silicone on hand for a perfect fit/seal.

Virgil H.: Fit same as previous drier vent!

Danceman: This is a great dryer vent. It is well-made and designed. It was easy to install and fit a standard 4" pipe. The air comes out of the vent with surprisingly great force (I was worried that the design would limit airflow, but that is not the case). In fact, I turned on my dryer after opening the lid and the cup shot into the air and out of the device. I like the fact that it is plastic and should reduce the heat flow into and out of the house. Best of all, it does not make any noise unlike the older flapper vent that I had which banged and clapped every time the wind blew and was driving me crazy. I also believe that the new vent should seal better than the old vent.

I highly recommend this product.

Jon D: Original vent cover on my house was broken, and caused literal frost buildup on the vent pipe indoors.

Upon opening the box this felt cheap and like it couldn’t possibly work, but my god, blew my expectations away. No frost build up, barley even a cool indoor pipe with outdoor temperatures dropping to -30c. Like I said, shockingly functional

G. Clarke: Another important consideration, which is often overlooked by homeowners, is easy access to permit cleaning your dryer vent of lint at least once a year. This increases dryer efficiency saves energy and may prevent a house fire as well.
Most homes have vented hoods or a louvered or flap-style dryer vent that only keeps out rodents. However, installing a ‘Dryer Vent Seal’ pop-top-style vent is an energy-efficient solution that accomplishes all of the above. When the dryer is on, the vent pops the floating shuttle and allows the moisture, heat, and lint to escape from the vent’s bottom, but then closes when the pressure stops and properly seals your home from the outside environment.
Installation is not difficult using a couple of basic tools. Made of high-impact plastic in an off-white colour, the ‘Dryer Vent Seal’ mounts over an existing 10 cm (4-inch) duct on siding, brick, or cement. You must supply the 6 mounting screws suitable for your particular application, and caulk any openings between the base of the elbow section and the wall with silicone. The exterior can be painted if desired. The damper section needs periodic cleaning by opening the lid and removing...

Mark: I’m just giving it 5 stars as it seems so much more superior to the traditional garbage vents I replaced. Lid clasps shut so cannot open in the wind and it faces a prevailing valley wind. You open(small squeeze and push) and can immediately see how easy it is to clean out. Cup inside is very easily removed and cleaning is going to be a snap. Only thing I will say is that the measurement on the base was slightly bigger than what was existing so I could not screw on without extra holes. I decided to just run a thick bead of silicone around the base and then attached the 2 top screws and it is solid. At this point it is a huge relief as the old one was terrible at letting in the cold wind from that prevailing wide open valley wind.

Jonah: Installed this dryer vent so we didn't have to clean the lint that kept collecting on the mouse-proofing wire mesh we had with the previous vent hood. Very easy to install, as others have noted and this is the best design I've seen for a mouse-proof dryer vent. The plastic appears to be very brittle and I was concerned about icicles falling off the roof and potentially breaking this vent cover. Rather than finding out if it would be a problem, I rigged up a "roof" over the vent cover. Any falling icicles would fall on it to prevent damage to this vent cover. It was due to the potential for breakage that I gave this 4/5 stars.

Steves_Reviews: Ok so the title really doesn't say much, this is a LARGE item and for many who like aesthetics of their exterior, they may not like this, here is why.
1. It's BIG, really big
2. It requires you to modify the old area a bit, a tiny bit
3. If your siding or exterior is cut around or cut to fit the exterior siding or stucco, you will have to cut the mount flange down a we bit
SO this DOES help in your quest to minimize the inflow of cold winter air into your home through your dryer a very common heat source or loss as it allows cold air to enter (simple thermodynamics), the old traditional dryer vent is useless against this after being in use and left uncleaned for months let alone years!
SO this uses the hot air from your dryer to "push" up a little cup to allow the hot air to escape.
Then, once the dryer has stopped, that "cup" drops down over the exhaust hole and thus seals the hole. Now it's not perfect as any bit of lint will hold the cup from sealing, BUT...it's a far better system than those useless shutters that stop working after oh, a few weeks.
Can it be be made better...yes but I like it and it does work so all in all, a massive win!

Amazon Customer: My previous dryer vent became useless after many years of use and the springs just gave up. So I ordered this with the hope that a simpler design would mean a better implementation.

PROS
- Simple design
- Easy to clean

CONS
- Could be hard to install
- No mounting hardware included (!)

The biggest issue with this product is that it can be hard to install especially if you're replacing another vent. In my case, I was concerned that the screw holes from the previous vent could interfere and prevent this vent from being secure on the house. I got lucky but if things were shifted just 1/2 inch, I would have been in trouble.

On the installation, I'd recommend having some Good Stuff spray insulation and outdoor silicone caulk on hand. When you take off the old dryer vent you will inevitable find that the original person who installed that vent did a poor job and there are large openings between the pipe and the house. Make sure you fill in those voids since that can cause air leakage or allow insects to enter the house.

When you line up the product to install it, use a generous amount of caulk the surfaces mating with the house. That will...
