Negative Positive
Title: Not so reliable
Review: I had a entirely new garage door and chamberlain door opener with an additional Chamberlain 940D Wireless, Keyless Entry System, 315 MHz opener outside on the wall.The opener worked for a short time and then intermittently worked and did not work. after awhile the buttons stopped working with the 4 digit code. (contact issue)also sometimes when you change the battery the code erases and you have to reenter it. not very good quality.
Is the review positive or negative?
