I am disappointed with this. There are two main problems.1. When the garage door hits the limit switch, the spring is not strong to stay in place to establish circuit contact/connection and stop the motor. In some cases, it snaps back and the motor keeps moving2. 1 of the 2 limit switch has wider guage for the point contacts (this point contact is where one clamps and connects the wire from the motor to the limit switch). A professional can file the gauge or expand the clamp to clip this. But it is still a hassle.I got another part for Amazon and it worked seamlessly and this is throw away for me.
