Review on 🐾 Premium Replacement Flaps for PetSafe Freedom Dog and Cat Doors - Effortless Replacement -Weather-Resistant Vinyl Material - Small, Medium, Large, X-Large Sizes by Tabitha Williams

I bought this to add to my one flap dog door. The wind keeps blowing it up and I've tried buying other magnets to keep it on the ground but it didn't work at all! So I bought this second one and attached it to a different valve so it closes on at least one side. It flexes a bit at the edge even after adjusting the top, but one that doesn't flex doesn't let cold air in, and that vent keeps it from blowing out. My dog doesn't notice his two so no need to worry. I would suggest having a second pair of hands when fitting the second one as it was difficult to saddle up the door and keep everything in order so you can put the screws back in. I did it myself but it was frustrating and took longer.
