PlexiDor pet doors manufactured prior to November 2017 have a five-year warranty. PlexiDors manufactured from November 2017 and forward have a ten-year warranty.
This video explains how the weather seal on a new PlexiDor or BiteGuard dog door is designed to overlap to make a good seal. This may make the panel not line up and the lock cam will hit the panel edge. This is normal and will go away with a little time as the ends of the weather seal soften. If this happens at first, just use your hands and push the panel forward gently and they will realign correctly.
They have hinges, like a door, so there's no loud flap slap or flexible materials. They lock easily, and most models come with a steel security plate for additional security when you are away.
