Great service, swift delivery and everything worked perfectly straight out of the box. Replacement Novoferm unit for a previous model of the same manufacturer. Slightly longer track so a little bit of adjustment but no problems. New unit is quieter and faster than the old. Simple to set up with the new fob able to map to my second door (old motor still going strong).
