Super quality !!! It was very easy to plug the Conversion set purely in the old shade. With my old (1 year old) Rollo the plastic holder was broken by the window, while there was a 80 Rollo. The Conversion Set of Liedeco was stuck installed quickly and simply or. The brackets are even made of metal !!! There is to a kind Kunstoffschuh that one then has to invert only over. It took me out of the old blind-pipe only pull out the tail and to plug the appropriate end back inside ... is important, however, that you order the set with the correct diameter. Thus the diameter of the old blind tube is meant. The repair kit is top quality! Too bad that you only need to buy an expensive blind that has so "cheap" brackets to make it then to make this set right "thing fixed."
