Speed Comfort Radiator fan

This SpeedComfort Trio Set was used on a radiator in our house for a few weeks before we had underfloor heating installed, so it is in nearly new condition (I just cannot figure out how to get it back into the box :) ). I thought it might be a gimmick, but it actually made quite a big difference to the room it was in which was too big for the radiator. Designed for radiators from 120cm to 180cm, it comes with a magnetic temperature sensor so the fans will only come on when the radiator is heating, helping to spread the hot air more quickly around the room.
