Review on Optimized Baboni Pet Door for Wall - Steel Frame & Telescoping Tunnel - Aluminum Lock - Double Flap Dog and Cat Door - Strong & Durable - Sizes: Small, Medium, Large by Amber Jackson

Our gentle giant German Shepherd broke down the door for our other pet, which was made of durable plastic, to get a big bad old squirrel into the garden. now we also know it wasn't energy efficient either! Within 10 minutes of installing this new pet door, we noticed a temperature difference! Our computer is right in front of the door and depending on the season it is always very cold or very warm. Because Texas is now hotter than Hades, it was warm in that little corner with the pet door and desk. no longer! We noticed immediately that it was getting cooler. Not only that, this pet door has a metal frame and better quality than our previous one. No complaints!
