If the product once programmed works relatively well. For programming it is another matter. It's very difficult is the millimeter the remotes must imperatively be back to back. the posture that you will adopt is totally improbable and inevitably painful if you do not succeed the first time. It would be pure chance by the way. I do not recommend this product until the programming is horribly painful and far from ergonomic and user friendly as can be the remote control to move to pin but it's obviously not the same price ....
