Pretty easy to install with the right tools. Comes with a drill bit for the screws that hold the two frame halves together. I like this design because it seems simple, strong, robust, and easy to maintain. the flap is thick and has some coating that prevents yellowing. I bought my first one in 2014 and 6 years later, it is still "clear". Some cloudiness but likely due to me scrubbing my dog's nose water and mud off of it. I purchased a second because I moved. In high wind, it will flap around a little. Maybe buy the weather strong version if you need it. Only one dog 65 lbs. The guard appears to be 1/4 acrylic, has a spring loaded screw to secure to the frame. Improvement from the last one I had, which was only spring loaded pin. If you knew where to push, you could bend and push the cover off from the outside. Threaded design should be more tamperproof.

Really happy with my door, thanks moorepet!!
