couod not give zero stars. Had the original pet door and LOVED it. It finally died after 6 years of constant use, so I decided to upgrade to the wifi version. Showed same specs so I thought there would be no problem. Put the front of the door in with no problem. I tried EVERYTHING to get this tunnel to fit. Made the hole in the wall bigger than the size showing on the website. Theirs thing would NOT fit. I went to order a new plastic tunnel that I knew would fit, and they don’t offer them anymore. Had to just cover my old plastic tunnel with water proof tape and use that one with the new door. Now, I can’t get the wifi door to sync with the app. Customer support couldn’t even help me. Very frustrating. Would buy the original door again, but seriously think twice about the WiFi door.

Excellent device and customer service. I did not realize hat the aluminum tunnel was included in the kit. I have to return the one I purchased

Fits perfectly in our exterior wall giving us access to our sliding door again. Love it!

Terrible design!!! It traps water in the tunnel and does not drain! The water covers the door sensor and the pets get stuck outside!
