The installation of the door opener was a bit more complex than indicated. Fits well in simple standard prefabricated garages, but otherwise problems with the dimensions. Had to be creative, to mount the drive very time consuming in the door area. Drive itself works without problems and so far runs pleasantly quiet. However, of the two supplied transmitters has nearly given up an already his mind. Battery ok, but it only works in exceptional cases. After only 4 months no quality evidence. Had already operate the emergency release several times! Complaints follows.
