Thank you for the video on your door opener. I suggest you show how the button works and how the door opener is installed on the door. Also show where the button should be installed so as not to have the door opening onto an individual opening the door. The door frame the button was installed on it looked like the button was placed a lot closer than 12' from the door and looked like it was close to where the door opens or closes. I could not tell. Thanks for you hard work on this video. Keep up the good work.
