Liftmaster 8500W DC Battery Backup Wall Mount Wi-Fi Garage Door Opener

Product Review (submitted on October 31, 2018):
Was requested several times to write a review only one week after installation. So far, so good, it will probably work for you for at least a week. The wireless communication was a pain, Chamberlain tech support courteous but told me their customers cannot expect them to know about all the firewall or software issues for setup. They are happy to sell though. I solved it myself by purchasing a WiFi repeater that communicates through my house electric lines. I could then place the Wi-Fi repeater right next to the opener and got it setup and working. Had to spend another $120.
