The unit is pricey for sure and it’s quality for the most part and seals pretty well. The problem I have had is the flaps are multiple pieces and when I say multiple, I mean 6 parts plus the magnets. And they must taste like bacon because I have a dog that’s really not a chewer but from anxiety I believe he chewed a part once and it’s been a problem ever since.
Granted this is not a fault of the manufacturer but I think if the flaps were more of a simple design, less pieces. Add the mechanical moving parts to the frame rather than having it all on the door, there would be less failures and issues. They will hang up if one of the pieces of the flap, that are attached get pulled a bit or snags. I believe the bottom part of the door was once metal but is now the bacon flavored plastic with the core part of the door a chewable rubber vinyl.
Granted dogs without anxiety issues I’m sure will be much more of a success but for me the flaps are the only thing that he will chew. Never messes with anything else. And if the plastic gets tweaked a little you can’t reshape it. So take your pic of one of the multiple parts to the door to reorder.
Will use mine going forward only when I’m home.
