On this roller shutter drive there is nothing wrong: - It can easily be installed - It can be programmed easily (in this version: the ups and downs have to be programmed to the time at which they are to be carried out, otherwise you have to dodge the display) - The attacks are approached exactly - It runs super-quiet - A light sensor is included in delivery - The light sensor is good as twilight switch and goes "felt" always at the preset value determined by the shutter down - Fair price (sometimes is cheap but scrap) - Very detailed user guide for laymen
