No issues at all so far
We installed this for our labrador retriever. it makes life that much easier for her and us. She can access the garden whenever she needs too, and if we need to be out for a little longer than usual its easy enough for her to relieve herself. Easy to install, i used a jigsaw to cut using the provided template and then installed. 1 hour job max. kept the door on while i did it. Had it for over a year and no issues at all
