I got my pet door installed today and am so happy with it. The installer called to let me know he was on his way and was here when he said he would be. He was professional and he even cleaned up after himself. He took the time to explain everything and to teach my dogs how to use it. They are happy and so am I. Thank you Tim and Desert Star Pet Doors. It is so nice to not have to get up all the time to let them in and out. They love the freedom and I can finally watch my movie all the way through.
