calimaero® 2 Pack Bird Stop Dryer Vent Grill Screen Guard Insert 8.8in x 8.8in Customizable 3inch to 8inch Stops Nesting in Bathroom Exhaust Vents

The screens --2 were included in the package-- were ample size and strength. I cut one with a heavy wire cutter tool and kept trimming it down to fit inside the round inside opening of the vent cover. Then, I cemented the screen in place with a silicone cement. I took care that the screen did not interfere with the fit of the cover or the motion of the flexible louvers. Waited 24 hours and put it back on with binder clamps. Seems just fine. I doubt the mice will get in now.

Given the price, I wasn't certain how solid a purchase this would be. I was very pleased with both the quality and ease of installation. While there were no installation instructions with the product, they are available in the product description on Amazon. It's pretty much measure, cut, install. It was so easy I ended up doing 2 more vents. One sheet (it comes with 2) handled all four rectangle vents. You simply removed the louvers place the cut screen piece into place, and put the louvers back on. I should note these were used on "non-laundry vents," and only fan exhaust vents. We will see how sturdy they screen is and if it really protects the vent entrance/exit.

Totally worth it and super easy to cut. I just did a few Zip ties and now my dryer won't fill up with walnuts again lol

No major issues. Product is as advertised and function as purposed.

Excellent product, easy to snip to size. Definitely keeping the birds out of our bathroom vents this season! Great value to fit multiple vents if needed. While it absolutely does its job, it looks sleek and not like we have added anything obtrusive to the house! Easily wipes clean.

Should have investigated how it was supposed to attach to vent before ordering.Just a piece of screen,not what I needed.

The screen material is easy to cut and bend to shape, but is also sturdy. It arrived promptly.

Good quality and attractive .
