Works perfectly! Have older car with semi-tired window motors. Still rolls them up and down fine. Wired to my alarm and it's a great convince! Works like normal switches if pressed longer then about 1 sec. A quick push and release and the window travels full length. Unit also has wire leads that I used to wire to a sunroof with relays to close roof when alarm is armed. Depending on your available mounting locations the wires could be a little short. Only bad thing about it! Well worth the time and money! Instructions are also adequate.
