## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for out garden shed
*by K***Q on June 27, 2018*

Installed these in the garden shed/greenhouse my husband built. They are great. They automatically open and close to vent hot air without the need for electricity. Almost like magic. Easy to install. A super value!

### ⭐⭐⭐⭐⭐ Wish they used phillips head screws
*by B***E on October 13, 2021*

I replaced my vents with these foundation vents around my house. They look nice as a finished project. The only suggestion I have for the manufacturer is to use phillips head screws rather than slotted screws

### ⭐ I purchased 8 of these vents. and 4 of ...
*by D***E on January 15, 2016*

I purchased 8 of these vents. and 4 of them did not close when the weather got cold, causing my pipes to freeze, Amazon did nothing for me, said my 30 days were up. We had very warm days , so I did not check them out. spend a lot of money on amazon, and I think they would have taken them back. Sorry to say I will spend my money somewhere else. Shame on you amazon
