Question: How many do you get for that price?
Document: It's hard to find vents in stores, so coming across them on Amazon.com made it simple. They are well made and perfectly fit the holes where my old ones fell out. The price is right, too. Now I have a few extras for next time. Prime delivery got them here quickly, too. I recommend these.
Who would think to order such a simple thing? My Home Depot had a vastly inferior product, not painted, no screen, for almost twice the unit price of these. Add in Prime shipping, and it is a slam dunk to buy. I ordered at the start of a re-roof job and received in time for my roofers to install.
Works perfectly for my application.
I used these to vent a worth farm that I made out of a plastic tub. They worked out great and were delivered very quickly.
I bought a pack of these to use as a drainage for a special sandbox project and these were perfect to act as drainage holes out the bottom and still prevent bugs and such from being able to come in.
Great product. Exactly as advertised. Item fit perfectly and looks great! Fast shipper, too. Very glad to have found this product.
