Took a few times to get the programing to take, hence 4 stars. But after several attempts it does do the job.

These work great. I highly recommend them. They work on my old garage door opener as well as the new one next to it. I'm embarrassed to say how many different interpretations of the instructions I tried before I guessed correctly how to program them.
The term "learn-button" refers to the program or learn-button on the door operating motor.
The term "program-button" refers to button 5 on the remote-control and is next to the row of DIP switches.
Identify the doors to be operated as door I and II. While programing the remote-control for door I, use button I. While programing the remote-control for door II, use button II. Repeating the setup procedure for each door will allow a single remote-control to operate one or two different types of doors.
For each door opener, identify its brand and the type of learn-button, located on the motor. Use the table in step 3 of the manufacturer's User Manual to determine the number of times that you will need to press the remote-control button I or II when programming the remote-control.
Remove the remote-control battery cover and locate the program-button (button 5).
Then do these steps within one minute to program the remote:
1. Press and hold the program-button on the remote-control until the blue light on the remote-control turns on, then release the program-button.
2. On the remote press the I or II button (corresponding to the door you are programming) the number of times indicated in the table in step 3 of the manufacturer's User Manual. Allow the blue light to flicker after each press of the button before pressing again.
3. Press the program-button on the remote to store the setting in the remote. The blue light will extinguish.
4. Press the motor learn-button. It will light up.
5. Press the I or I button (corresponding to the door you are programming) one last time. The light on the motor learn-button will extinguish.
Example 1:
1. Press and hold the program-button on the remote until the blue light comes on.
2. Since the motor is a Chamberlain and has a yellow learn-button, press the I button on the remote 8 times, allowing the blue light to flicker after each press.
3. Press the program-button on the remote to store the setting in the remote. The blue light will extinguish.
4. Press the motor learn-button. It will light up.
5. Press the I button on the remote. The motor learn-button will extinguish.
6. Test the remote control.
Example 2:
1. Press and hold the program-button on the remote until the blue light comes on.
2. Since the motor is a Chamberlain and has a purple learn-button, press the II button on the remote 3 times, allowing the blue light to flicker after each press.
3. Press the program-button on the remote to store the setting in the remote. The blue light will extinguish.
4. Press the motor learn-button. It will light up.
5. Press the II button on the remote. The motor learn-button will extinguish.
6. Test the remote control.

This product is worth the money, as a woman who knows nothing about garages or garage doors, I was able to figure it out and it works flawlessly. I love that I can be down the road and it still sends the signal without having to double push. Just get it!

This programs easily, and works. Guess it works almost to well. It's very sensitive (to sensitive). Not kidding. Barely touch it and doors opened or closed.
Gave a 4 because of how sensitive it is.

Once I figured out what "press and release this button certain times continuously corresponding your brand" meant, these controls were a breeze to set up. I really like being able to carry one control that can open both doors. It received 4 stars instead of 5 for the poorly translated instructions and for the fact that it only comes with a clip. I really wanted something I could hook to a strap.
