The plastic part which was at least 25 years old broke and after looking through their online catalogue it was in stock and arrived promptly enabling a good repair. Thanks due.

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).

Efficient service and order arrived promptly. The only area that could be criticised was the lack information regarding expected delivery date.
